title: 2-Hydr-oxy-N'-[(1E,2E)-3-phenyl-prop-2-enyl-idene]benzohydrazide.
abstract: In mol-ecule of the title compound, C(16)H(14)N(2)O(2), the two aromatic rings form a dihedral angle of 6.93 (3)° and an intramolecular N-H⋯O hydrogen bond occurs. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into zigzag chains running in the [10] direction.
