Crystal structures of MoSi₂, CrSi₂ and TiSi₂

Figure 20: The crystal structures of MoSi₂, CrSi₂, and TiSi₂. All of these structures contain hexagonal close-packed layers TSi₂; one of these is shown in the upper left-hand corner. The positions of the transition metal atoms of adjacent layers above and below are marked with small black dots in this drawing. The three structures have the stacking sequences AB (MoSi₂), ABC (CrSi₂), and ABCD (TiSi₂), respectively. The hexagons connecting the silicon atoms around a transition metal atom serve as guides for the eye.
