摘要：

In the the asymmetric unit of the title compound, C19H15ClN2O2, there are two symmetry-independent molecules, which adopt similar conformations. The largest difference is observed in the dihedral angles between the phenyl and the pyrazole fragments [17.00 (12) and 23.42 (10)degrees]. A strong intramolecular O-H center dot center dot center dot O hydrogen bond with the S (6) motif is observed in both molecules. Pairs of pi-pi stacking interactions between the phenyl groups [centroid-centroid distances = 3.6627 (13) and 3.7156 (14) angstrom] assemble the molecules into two types of centrosymmetric dimers. Weak C-H center dot center dot center dot O interactions connect molecules into chains along the b axis.
