title: 1-(4-Chloro-phen-yl)-3-phenyl-1H-pyrazol-5(4H)-one.
abstract: 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.
