title: 3-Oxo-N',2-diphenyl-2,3-di-hydro-1H-pyrazole-4-carbohydrazide.
abstract: In the title compound, C16H14N4O2, the pyrazole ring makes a dihedral angle of 10.49 (8)° with its N-bound phenyl group, while it is nearly perpendicular to the other phenyl ring [dihedral angle = 88.47 (5)°]. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O and N-H⋯O hydrogen bonds. In the crystal, the packing involves sheets of mol-ecules parallel to (100) linked by N-H⋯O hydrogen bonds. A C-H⋯O interaction is also observed.
