Four compounds (1d, 1e, 1h, 1p) out of twelve N-substituted S-methyl-N'-tosyl-isothioureas were shown to form polymorphic modifications.Attempts were made to isolate each single specimen and to characterize it by means of differential scanning calorimetry and infrared spectroscopy.The results clearly revealed that both different hydrogen bonding and conformational effects are responsible for the formation of the polymorphic species.With the help of (15)N labeled compounds the presence of the sulfonylimino structure in any modification was proved.The ν(NH) and δS(SO2) band positions are used to divide the polymorphs into two groups A and B.
