Crystal structure of (E)-2-[(2S,5R)-2-isopropyl-5-methylcyclohexylidene]hydrazine-1-carbothioamide

What is it about?

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-H...S 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)].
