title: 3-(4-Chloro-phen-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde.
abstract: In the title compound, C(16)H(11)ClN(2)O, the chloro-substituted phenyl ring is disordered over two positions with refined site occupancies of 0.503 (2) and 0.497 (2). The dihedral angle between the pyrazole and phenyl rings is 7.93 (7)°. The pyrazole ring also forms dihedral angles of 24.43 (9)° and 28.67 (9)° with the disordered chloro-substituted benzene ring. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds, generating R(2) (1)(7) and R(2) (2)(10) ring motifs. π-π inter-actions between the pyrazole and phenyl rings [centroid-centroid distance = 3.758 (1) Å] further stabilize the crystal structure.
