نویسندگان
چکیده
The title compound, C(20)H(16)N(2)O(2), was synthesized by the reaction of 2-hydroxy-benzohydrazide with diphenyl-methanone. The dihedral angle between the phenyl rings is 76.28 (11)°. The amino H atom is involved in an intra-molecular N-H⋯O hydrogen bond. In the crystal structure, the hydr-oxy groups and carbonyl O atoms form inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into chains running along the b axis.
