چکیده
The title compound, C(23)H(19)N(3)O(2), was synthesized by the 1,3-dipolar cyclo-addition reaction of N-phenyl-α-diazo-acetamide and chalcone. In the mol-ecule, the pyrazoline ring assumes an envelope conformation. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

In the title compound, C(22)H(18)N(2)O, the pyrazole ring is almost planar (r.m.s. deviation = 0.0098 Å) and its mean plane makes dihedral angles of 62.2 (2), 87.2 (2) and 8.0 (2)° with the phenyl and benzoyl rings, respectively. The crystal packing is stabilized by π-π stacking inter-actions [centroid-centroid distance = 3.658 (2) Å] and weak inter-molecular C-H⋯O hydrogen bonds.
