N2 - The asymmetric unit of the title compound, C17H11Cl3N2O2, contains two independent mol-ecules; the pyrazole rings are oriented with respect to the chloro-phenyl and dichloro-phenyl rings at dihedral angles of 43.00 (3) and 65.06 (4)°, respectively, in one mol-ecule, and 51.17 (3) and 69.99 (3)°, respectively, in the other. Pairs of inter-molecular O - H⋯O hydrogen bonds link the mol-ecules into dimers. In the crystal structure, there are π-π contacts between the pyrazole rings and dichloro-phenyl rings [centroid-centroid distances = 3.859 (3) and 3.835 (3) Å].
