N′-(4-Diethylamino-2-hydroxybenzylidene)-4-(dimethylamino)benzohydrazide methanol monosolvate

Abstract

The title compound, C20H26N4O2·CH3OH, was prepared by the reaction of 4-diethylamino-2-hydroxybenzaldehyde with 4-(dimethylamino)benzohydrazide. The dihedral angle between the two benzene rings is 13.6 (3)° and an intramolecular O—H...N hydrogen bond generates an S(6) ring. In the crystal, the hydrazone and methanol molecules are linked through intermolecular O—H...O and N—H...O hydrogen bonds, forming chains along a.
