In the title compound, C12H15N3S, the molecule deviates slightly from planarity, with a maximum deviation from the mean plane of the non-H atoms of 0.2756 (6) Å for the S atom and a torsion angle for the N—N—C—N fragment of −7.04 (16)°. In the crystal, molecules are linked by N—HS hydrogen-bond interactions, forming centrosymmetric dimers. Additionally, one weak intramolecular N—HN hydrogen-bond interaction is observed. The crystal packing shows a herringbone arrangement viewed along the c axis.

The title compound, C11H21N3S, consists of a menthone moiety attached to an extended thiosemicarbazone group with the N—N—C—N torsion angle being 11.92 (16)°. The cyclohexane ring has a chair conformation and the conformation about the C=N bond is E. In the crystal, molecules are linked via pairs of N—HS hydrogen bonds, forming chains along the a axis. The absolute structure could be assigned with reference to the starting material, i.e. enantiopure (−)-menthone [Flack parameter = 0.05 (5)].
