    The D centered cell is the used for the rhombohedral description of the hexagonal lattice. Six right-handed D cell with basis vectors of equal length are obtained from the hP cell by means of one of the following transformation matrices:

    D1: 10-1/01-1/111 D2: -101/0-11/111

    the other four D cells are obtained by cyclic permutation of the basis vectors.

    The resulting hD cell has centering nodes at 1/3,1/3,1/3 and 2/3,2/3,2/3
