Crystal structures of two hydrazide derivatives of mefenamic acid, 3-(2,3-dimethylanilino)-N′-[(E)-(furan-2-yl)methylidene]benzohydrazide and N′-[(E)-benzylidene]-2-(2,3-dimethylanilino)benzohydrazide
The conformation about the central benzene ring in the molecule of (I), C20H19N3O2, is partially determined by an intramolecular N—H...O hydrogen bond. In the crystal, chains parallel to the c axis are generated by intermolecular N—H...O hydrogen bonds with the chains assembled into a three-dimensio...
