Description
Summary:The molecule of the title benzohydrazide derivative, C15H14N2O4, is twisted and exists in a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 56.86 (9)° and the C atom of the methoxy group deviates slightly [C—O—C—C = −10.4 (3)°] from its attached benzene ring. An intramolecular O—H...N hydrogen bond generates an S(6) ring. In the crystal, molecules are linked by N—H...O and bifurcated N—H...(O,O) hydrogen bonds, as well as weak C—H...O interactions, into two-dimensional networks lying parallel to the bc plane. A weak C—H...π interaction also occurs.
