5-(4-Chloro-phen-oxy)-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde.

In the title compound, C17H13ClN2O2, the phenyl and chloro-benzene rings are inclined to the central pyrazole ring at 40.84 (9) and 65.30 (9)°, respectively. In the crystal, pairs of C-H⋯π inter-actions link the mol-ecules into inversion dimers and C-H⋯O hydrogen bonds link these dimers into columns extended in [010]. The crystal packing exhibits short inter-molecular O⋯Cl contacts of 3.0913 (16) Å.
