Figure 5
Packing of molecules in cimetidine form C polytype 6M. The ac (left) and ab (right) structure projections are shown. Red circles mark the centres of molecules associated with the positions of S1 atoms. L and L' are defined by y [asymptotically equal to]

0 and y

0.5, respectively, for the centres of the molecules. I, II and III denote the corresponding molecules.
