3,4-Dihydroxy-N′-(2-hydroxybenzylidene)benzohydrazide–methanol–water (2/1/3)

Abstract

The asymmetric unit of the title compound, C14H12N2O4·0.5CH4O·1.5H2O, consists of two Schiff base molecules, three water molecules and one methanol molecule. The dihedral angle between the two benzene rings is 7.8 (2)° in one of the molecules and 4.0 (2)° in the other. Intramolecular O—H...O and O—H...N hydrogen bonds are observed. Molecules are linked into a three-dimensional network by O—H...O and N—H...O intermolecular hydrogen bonds.
