Crystal structure and Hirshfeld surface analysis of (E)-4-chloro-N-{2-[2-(4-nitro-benzyl-idene)hydrazin-1-yl]-2-oxoeth-yl}benzene-sulfonamide N,N-di-methyl-formamide monosolvate.

The asymmetric unit of the title compound, C(15)H(13)ClN(4)O(5)S·C(3)H(7)NO, contains one mol-ecule each of the Schiff base and the solvent di-methyl-formamide. The hydrazone group adopts an E configuration about the C=N bond. The dihedral angle between the two aromatic rings is 86.58†(2)°. In the crystal, pairs of N-H⋯O hydrogen bonds between centrosymmetrically related mol-ecules generates rings with an R(2)(2)(10) graph-set motif. The dimers are further linked via N-H⋯O and C-H⋯O hydrogen bonds, leading to the formation of R(3)(3)(11) ring motifs. C-H⋯π inter-actions are also observed. The inter-molecular inter-actions in the crystal structure were qu-anti-fied and analysed using Hirshfeld surface analysis, which indicates that the most significant contacts in packing are O⋯H/H⋯O (31.3%), followed by H⋯H (25.4%) and C⋯H/H⋯C (13.0%).
