Crystal structure of ( E )-2-[3-( tert -but-yl)-2-hy-droxy-benzyl-idene]- N -cyclo-hexyl-hydrazine-1-carbo-thio-amide.

In the title compound, C18 H27 N3 OS, 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.
