Abstract

In the title compound, C₁₈H₂₇N₃OS, the cyclo-hexane ring has a chair conformation. The azomethine C=N double bond has an E configuration. The nearly planar hydrazinecarbo-thio-amide moiety and substituted benzene ring are twisted by 31.13 (5)° relative to each other. The amide moiety and the cyclo-hexane ring are almost perpendicular to each other; a similar conformation was previously observed in reported structures. In the crystal, mol-ecules are linked by N-H⋯S hydrogen bonds, forming inversion dimers with an R ² ₂(8) ring motif.

Keywords: carbothioamide Schiff base; crystal structure; cyclohexylhydrazine; soft Lewis base.
