Benzyl 3-(3,4,5-trimethoxybenzylidene)dithiocarbazate

Abstract

The title compound, C18H20N2O3S2, a dithiocarbazate derivative, adopts an E conformation about the C=N bond. The trimethoxyphenyl group and the dithiocarbazate fragment lie almost in the same plane, with the mean plane of the dithiocarbazate unit being inclined to the trimethoxyphenyl ring by 13.34 (6)°. The aromatic rings are inclined to one another by 75.30 (9)°. In the crystal, molecules are linked via pairs of N—H...S hydrogen bonds, forming inversion dimers with an R22(8) ring motif. The dimers are linked via C—H...O hydrogen bonds, forming undulating sheets lying parallel to (103) which are linked via C—H...π interactions, forming a three-dimensional supramolecular structure.
