Description:
The equimolar reaction between a racemic mixture of (R)- and (S)-camphorquinone with thiosemicarbazide yielded the title compound, C11H17N3OS [common name: (R)- and (S)-camphor thiosemicarbazone], which maintains the chirality of the methylated chiral carbon atoms and crystallizes in the centrosymmetric space group C2/c. There are two molecules in general positions in the asymmetric unit, one of them being the (1R)-camphor thiosemicarbazone isomer and the second the (1S)- isomer. In the crystal, the molecular units are linked by C—H...S, N—H...O and N—H...S interactions, building a tape-like structure parallel to the (overline{1}01) plane, generating R 2 1(7) and R 2 2(8) graph-set motifs for the H...S interactions. The Hirshfeld surface analysis indicates that the major contributions for crystal cohesion are from H...H (55.00%), H...S (22.00%), H...N (8.90%) and H...O (8.40%) interactions.
