(E)-1-[3-Methoxy-4-(4-methylphenylsulfonyloxy)benzylidene]-2-(4-nitrophenyl)hydrazine: a monoclinic polymorph

X. Chen and M. Yu

Abstract: In the title compound, C₂₁H₁₉N₃O₆S, the vanillin group makes dihedral angles of 56.00 (7)° and 7.22 (8)° with the 4-methylbenzene ring and the nitrophenylhydrazine ring, respectively. The crystal packing is stabilized by intermolecular N-HO hydrogen bonds and weak, non-classical intermolecular C-HO hydrogen bonds that link adjacent molecules into one-dimensional extended chains.
