Cimetidine, C10H16N6S, form C: crystal structure and modelling of polytypes using the superspace approach

Figure 1
The molecular conformations of cimetidine forms A and D. The figure was produced using the PLATON program (Spek, 2009

) on the basis of atomic parameters reported by Hadicke et al. (1978

) and Shibata et al. (1983

) for A and D, respectively.
