In the crystal of the title compound, C(15)H(11)ClN(2)O, the molecules are linked by C-H⋯O and weak C-H⋯π inter-actions. The chloro-phenyl and phenyl rings are twisted with respect to the central pyrazolone ring, making dihedral angles of 18.23 (8) and 8.35 (8)°, respectively. The N-N and C=O bond lengths are comparable to those reported for pyrazolone compounds.
在标题化合物C₁₅H₁₁ClN₂O的晶体中，分子通过C-H⋯O和弱C-H⋯π相互作用相连。氯苯基和苯基环相对于中心吡唑啉酮环发生扭曲，二面角分别为18.23 (8)°和8.35 (8)°。N-N和C=O键长与吡唑啉酮化合物报道的键长相当。
