5-(4-Chloro­phen­yl)-1-(2,4-dichloro­phen­yl)-4-methyl-1H-pyrazole-3-carboxylic acid

The asymmetric unit of the title compound, C(17)H(11)Cl(3)N(2)O(2), contains two independent mol­ecules; the pyrazole rings are oriented with respect to the chloro­phenyl and dichloro­phenyl rings at dihedral angles of 43.00 (3) and 65.06 (4)°, respectively, in one mol­ecule, and 51.17 (3) and 69.99 (3)°, respectively, in the other. Pairs of inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into dimers. In the crystal structure, there are π–π contacts between the pyrazole rings and dichloro­phenyl rings [centroid–centroid distances = 3.859 (3) and 3.835 (3) Å].
