Crystal structure of 4-[(E)-(2-carbamothioylhydrazinylidene)methyl]benzoic acid

Abstract

The title compound, C9H9N3O2S, is close to planar with an r.m.s. deviation of 0.032 Å. An intramolecular N—H...N hydrogen bond closes an S(5) ring. In the crystal, molecules are connected into inversion dimers of the R22(8) type by pairs of O—H...O interactions. The dimers are further connected by pairs of N—H...S interactions, which also complete R22(8) ring motifs. The chains of dimers are cross-linked by N—H...O bonds and hence R42(28) rings are completed. Taken together, these interactions lead to infinite sheets propagating in the (122) plane.
