Crystal structure of benzyl (E)-2-(3,4-dimethoxybenzylidene)hydrazine-1-carbodithioate

Abstract

The title compound, C17H18N2O2S2, synthesized via a condensation reaction between S-benzyl dithiocarbazate and 3,4-dimethoxybenzaldehyde, crystallized with two independent molecules (A and B) in the asymmetric unit. Both molecules have an L-shape but differ in the orientation of the benzyl ring with respect to the 3,4-dimethoxybenzylidine ring, this dihedral angle is 65.59 (8)° in molecule A and 73.10 (8)° in molecule B. In the crystal, the A and B molecules are linked via pairs of N—H...S hydrogen bonds, forming dimers with an R22(8) ring motif. The dimers are linked via pairs of C—H...O hydrogen bonds, giving inversion dimers of dimers. These units are linked by C—H...π interactions, forming ribbons propagating in the [100] direction.
