N′-(2-Hydroxy-1,2-diphenylethylidene)benzohydrazide

Abstract

In the title compound, C21H18N2O2, the amino group is involved in an intramolecular N—H...O hydrogen bond. The rings make dihedral angles of 37.9 (2), 64.4 (2) and 83.6 (2)°. In the crystal, intermolecular O—H...N and O—H...O hydrogen bonds link the molecules into chains running along [100].
