N′-[(5-Methyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)(thiophen-2-yl)methylidene]benzohydrazide
In the title compound, C22H18N4O2S, the seven-membered ring generated by an intramolecular N—H
O hydrogen bond adopts an envelope conformation in both of the two independent molecules in the asymmetric unit. In the crystal, molecules are linked into C(9) chains along [100] by N—HO hydrogen bonds. The molecules are also weakly linked by C—HO and C—HN interactions, forming dimers with edge-connected R22(9) rings. The dimers are interlinked by further weak C—HN hydrogen bonds into chains along [010].
