synthesised as mimics of an R2/2(8) motif, which occurs in one crystal polymorph of sulfathiazole and in several polymorphs of sulfapyridine. When present in crystallisations of sulfathiazole and sulfapyridine, these mimics were found to have little or no effect under crystallisation conditions that favour the formation of polymorphs not containing R2/2(8) motifs. However, the mimics were found to completely
