Abstract: There are two independent molecules in the asymmetric unit of the title compound, C₂₈H₃₂ClN₃OS (systematic name: 2-chloro-N-{5-[(1R,4aS,10aR)-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthren-1-yl]-1,3,4-thiadiazol-2-yl}benzamide). In each molecule, the cyclohexyl ring attached to the thiadiazole fragment adopts a classic chair conformation with two of its two methyl groups in the axial positions. In the crystal, pairs of intermolecular N-HN hydrogen bonds link the molecules into centrosymmetric dimers, which are further linked via C-H interactions.
