Abstract: In the title compound, C17H14Cl2N2O, the dihedral angles between the pyrazole ring and the mean planes of the benzene and chloro-substituted benzene rings are 75.97 (1) and 16.63 (1)° respectively. In the crystal, two weak C-HO intermolecular hydrogen bonds and - stacking interactions [centroid-centroid distances = 3.774 (4) and 3.716 (7) Å] are observed.
