title: N'-[(E)-4-Benz-yloxy-2-hy-droxy-benzyl-idene]benzohydrazide.
abstract: The title compound, C(21)H(18)N(2)O(3), exists in the E conformation with respect to the azomethane C=N double bond. The central benzene ring is almost coplanar with one of the substituent benzene rings [dihedral angle = 1.74 (5)°] and is approximately orthogonal to the other benzene ring of the mol-ecule [dihedral angle = 86.61 (7)°]. An intra-molecular O-H⋯N hydrogen bond occurs. The crystal packing is dominated by N-H⋯O hydrogen bonds, which lead to an infinite chain running parallel to [010].
