4'-{[Benzoyl(4-nitrophenylhydrazono)methyl]sulfonyl}acetanilide

W. M. Wolf

Abstract: The conformation of the title compound, C₂₂H₁₈N₄O₆S, is stabilized by a strong resonance-assisted intramolecular hydrogen bond linking the hydrazone moiety and the sulfonyl group. The resulting six-membered ring is practically planar. Short intramolecular contacts link oppositely charged atoms of the sulfonyl and -carbonyl groups. The crystal packing is influenced by intermolecular hydrogen bonds involving the -carbonyl O atoms and the N-H bonds of the terminal acetamide moieties.
