Nomenclature of Coordination Complexes

    Table of contents
    No headers
    Add hyperlinking.

    You want the sentence structure to be as simple as possible: ie. you will want to omit "are contrived of"...(wrong usage)

    Use subscripts and superscripts.

    Add pictures and examples of various "dentate" ligands.

    The intro looks great so far. You're probably still working on it, but including examples would be great.

    I noticed that you had a section with prefix for denotation of ligands. You might want to specify about the rule of using the prefix mono-.

    This topic can get very confusing when it's being explained, using A LOT of different kinds of examples will help.

    Good job so far with the introduction and descriptive steps of naming compounds!

    Looks great so far. I realize you may already be planning to do this, but you can link to other modules (for example, the 'Lewis concept of Acids and Bases' module to expand on the second paragraph).

    this is just a little detail, but you should reformat:

    "The cation [Cr(H2O)4(NH3)]+2 is written before SO4-2."

    its the second to last sentence under "writing coordination complexes, " probably just forgot to unclick the superscript button.

    Good job Char. Only thing I was suggest to do is to add some images of ligands as well as practice probelms to make sure that the reader is understanding the concept

    You should add more problems and also mix it up a little bit such as writing the coordination complex and asking for the names, or give the names and ask for the coordination complexes.

    Chem 2C Module Review

    Module Title: NOMENCLATURE FOR COORDINATION COMPLEXES
    Module Author(s): JUSTIN HOSUNG LEE

    Specific Questions:
    (1) Does the module fall within the scope of the Journal? THE MODULE FALLS WITHIN THE SCOPE OF THE JOURNAL HOWEVER THE JOURNAL WAS EXTREMELY BRIEF AND DID NOT REALLY HELP EXPLAIN THE SUBJECT CONTENT AT ALL.
    (2) Are any statements made which you consider unjustifiable? NO, THE CONTENT IS JUSTIFIABLE
    (3) Are there any apparent errors of fact or logic? THE CONTENT SEEMS TO BE CORRECT IN ITS FACTS
    (4) Is the length of the module appropriate? MODULE LENGTH IS ABOUT AVERAGE. THERE COULD BE MORE EXAMPLES
    (5) Is the summary informative? THE INTRODUCTION GIVES A VERY NICE DESCRIPTION OF THE REASONING BEHIND NOMENCLATURE OF THESE COORDINATION COMPOUNDS AND WHY STUDENTS MUST STRUGGLE TO LEARN THEM.
    (6) Are the figures appropriate? THE FIGURES ARE MEDIOCRE. THEY COULD DEFINATELY BE IMPROVED ON BY ADDING MORE FIGURES, ENANTIOMERS, HOW ETHYLENEDIAMENE BONDS IN A COORDINATION COMPLEX. THE CHARD DEPICTING THE MONODENTATE LIGANDS IS A LITTLE HARD ON THE EYES--IT COULD BE FORMATTED A LITTLE BIT NICER.
    (7) Is the module format useful (e.g. not excessive colors or awkward formulations)? OVERALL, THE FORMAT IS LOGICAL AND FOLLOWS A CLEAR PATTERN

    Recommendation:
    Select one: 2) Publish with minor revisions

    Synopsis: NOMENCLATURE OF COORDINATION COMPLEXES INVOLVES A LIGAND WHICH CAN BE MONODENTATE OR POLYDENTATE AND A METAL. THE METAL CENTER HAS THE POSITIVE CHARGE AND THE LIGAND HAS NO CHARGE OR A NEGATIVE CHARGE. THERE ARE SEVERAL RULES FOR NAMING COMPLEXES WHICH INCLUDE NUMERICAL PREFIXES, SPECIAL NAMES FOR LIGANDS (EX- AQUA FOR H2O). WHEN NAMING, ONE MUST TAKE INTO CONSIDERATION THE OVERALL CHARGE OF THE COMPLEX.

    Details: In this section provide a detailed critical review of the module. This includes format, overview, mistakes etc. Confirm with the ChemWiki FAQ for guidelines and specific details. OVERALL, I FEEL THIS MODULE DID AN AMAZING JOB EXPLAINING AND TEACHING HOW TO NAME COORDINATION COMPLEXES. IT WAS VERY USE FRIENDLY. I ESPECIALLY LIKED HOW THE CREATOR PROVIDED EXAMPLES AFTER EACH NEW NOMENCLATURE RULE. THE FORMAT OF THE MODULE WAS ALSO WELL DONE BECAUSE IT FOLLOWED A FORMAT THAT BUILT UPON PREVIOUS RULES WHICH EACH RULE BECOMING MORE ADVANCED. MY ONLY CONCERN IS THAT THERE WAS A LACK OF PICTURES SHOWING WHAT A COMPLEX LOOKS LIKE. THE CREATOR MAY WANT TO INCLUDE 3-D IMAGES OF SOME COMPLEXES.

    Specific Points to fix:
    1- IMAGES/PICTURES OF COORDINATION COMPLEXES
    2- A NICER FORMAT FOR THE MONODENTATE LIGAND TABLE WOULD BE HELPFUL
    3- SEPARATE THE QUESTIONS FROM THE ANSWERS. STUDENTS CAN SEE THE ANSWER WHILE THEY ARE READING THE QUESTION.
    4- TRY LINKING TO OTHER CHEMWIKI MODULES SUCH AS THE "LIGANDS" MODULE.
    5- MORE PRACTICE PROBLEMS. FOR ME AT LEAST, THE BEST WAY TO LEARN THESE RULES WAS TO DO MANY PRACTICE PROBLEMS.

    Module Title: Nomenclature for Coordination Complexes
    Module Author(s): Justin H. Lee

    Specific Questions:
    1) The module falls within the scope of the journal.
    2) Statements are objective and above suspicion.
    3) As far as I can see the facts and logics of this module remain correct.
    4) The length could be shorter.
    5) Very informative and well-detailed.
    6) Very appropriate figures, helps to understand. More content would require more figures.
    7) The module format is a bit chaotic; greater separation between figures and paragraphs would be better.

    Recommendation: Publish with minor revision.

    Synopsis: The nomenclatures for coordination compounds are composed of the name of ligands and the attached central metal, each complex ion. Three steps to constructing the name are as follows: Anion ligands are named first, the central metal second, and the oxidation state denoted by a roman numeral afterwards. Various rules regarding naming exists, such as replacing “ide” with “o”, “ite” with “ate”, and “ito” with “ato”. Neutral molecules as well as metal centers have their individually unique names for coordination complexes.

    Details: The overall format of the module is a bit chaotic, with tables and figures mingled with the paragraph and other contents. They could be revised, better organized. As for mistakes, I do not see any obvious ones, but due to the chaotic nature of the module such mistake could have slipped past my radar. The overall recommendation and criticism would be directed towards the organization, or rather the lack of, within the module.

    Specific Points to fix:
    1. More constructive and detailed figures.
    2. More examples may be needed.
    3. Present clear and structured figure that presents overall summary of the module.
    4. Longer details regarding history and background.
    5. More hyperlinks to other articles.

    Module Title: Nomenclature for Coordination Complexes
    Module Author(s): Justin H. Lee

    Specific Questions:
    1) yes
    2) statements are justifiable
    3) facts are correct.
    4) could be condensed to make room for other information.
    5) Very informative about the rules to naming.
    6) Very appropriate figures that help readers understand better
    7) formatting is good, could just group the rules together instead of separating into two steps

    Recommendation: Publish with minor revision.

    Synopsis: The nomenclatures for coordination compounds are composed of the name of ligands and the attached central metal, each complex ion. Naming orders: Anion ligands are named first, the central metal second, and the oxidation state denoted by a roman numeral afterwards. Follow the rules regarding naming exists.

    Details: I would recommend using tables so the rules and the names seem more organized so the format is easier to follow
    Specific Points to fix:
    1. More figures/pictures.
    2. More examples and practices.
    3. some history and background.
    4. use tables
    5. Reformatting the module

    Specific Questions:
    (1) Does the module fall within the scope of the Journal? Yes
    (2) Are any statements made which you consider unjustifiable? No
    (3) Are there any apparent errors of fact or logic? No
    (4) Is the length of the module appropriate? It could be shorter and more concise.
    (5) Is the summary informative? Yes
    (6) Are the figures appropriate? Yes
    (7) Is the module format useful? Yes, however, there could be slight re-organization.

    Recommendation: 2) Publish with minor revisions

    Synopsis: To name coordination complexes you must name the ligands in alphabetical order, followed by the metal and its oxidation state. There are three types of ligands, monodentate, bidentate and polydentate. There are many ligands that just simply have to be memorized.

    Details: The module is very well done, and there is a lot of information. However, the module does seem to overload its reader, so it could be shortened to remain concise and to the point. I love all the examples.

    Specific Points to fix:
    1. Condense the module, take out parts that are redundant/confusing, etc.
    2. There could be more figures included in the module.
    3. I would change the format of the practice questions so that the answers can be highlighted when needed.
    4. The module could be a little more colorful/ add more images
    5. Use a table for the monodentate ligands instead of bullets to make it easier to read.

    Module Title: Nomenclature for Coordination Complexes


    Module Author(s): Justin Lee


    Specific Questions:


    (1) Does the module fall within the scope of the Journal? Yes


    (2) Are any statements made which you consider unjustifiable? No


    (3) Are there any apparent errors of fact or logic? No


    (4) Is the length of the module appropriate? Yes, but a bit lengthy in my opinion


    (5) Is the summary informative? Yes


    (6) Are the figures appropriate? Yes


    (7) Is the module format useful? Yes, but could be expanded on some areas, such as the steps



    Recommendation:


    Select one: 2) Publish with minor revisions.



    Synopsis: In order to name a coordination complex, numerous rules must be followed. First, anion ligands are named then the central metal and then the oxidation state must be noted last. Also, there are numerous amounts of ligands that must be memorized, and different names and charges on them.



    Details: The module was very straightforward on the rules part. However, I think it could be improved by adding emphasis on the steps. The steps were only mentioned in detail in the beginning. I think a constant reminder should be emphasized throughout the module, because well... the steps are the biggest part in naming the complexes. Examples were awesome and very useful.



    Specific Points to fix:


    1. Lots of text... could be remedied if you make some rules into chart format or add some pictures


    2. Some backround information on the rules would be interesting


    3. Link some key terms to other articles


    4. Add some more practice problems


    5. Some parts seem quite long, as the text seems to keep going. However, I think this can be easily remedied by either shortening or condensing some parts or spreading some pictures throughout the article.
