N′-(2-Hydroxy-4-methoxybenzylidene)-4-methylbenzohydrazide

Abstract

The asymmetric unit of the title compound, C16H16N2O3, contains four independent molecules with different conformations; the dihedral angles between the two benzene rings in the molecules are 39.7 (3), 45.4 (3), 50.6 (3) and 51.6 (3)°. Intramolecular O—H...N hydrogen bonds are observed in the molecule. In the crystal, N—H...O hydrogen bonds link the molecules into two crystallographically independent chains propagating in [010], and each chain is formed by two alternating independent molecules. Weak C—H...O interactions also occur.
