The crystallography of hexagonal hemicarbides of the sixth group transition metals (Mo2C, W2C) has been investigated by many workers, and an up to date review is presented herein (Section 1); it appears that controversies concerning the various ordered structures (i.e. C6, ~-Fe2N and (-Fe, N-type ph
