3-Hydroxy-N′-[(Z)-(5-methyl-2-furyl)methylidene]naphthalene-2-carbohydrazide

Abstract

The asymmetric unit of title compound, C17H14N2O3, contains three independent molecules. In one of these molecules, the 5-methyl-2-furyl group is disordered over two sets of sites with an occupancy ratio of 0.747 (3):0.253 (3). In the two ordered molecules, the furan and naphthalene rings are oriented at dihedral angles of 11.05 (12) and 32.2 (5)°. In the disordered molecule, the furan rings with major and minor occupancies are oriented at dihedral angles of 41.4 (2) and 26.6 (13)°, respectively, with the corresponding naphthalene ring. An intramolecular O—H...O hydrogen bond occurs within each molecule. In the crystal, molecules are linked by N—H...O, N—H...(N,O) and C—H...O interactions.
