title: Crystal structure of [1-(3-chloro-phen-yl)-5-hy-droxy-3-methyl-1H-pyrazol-4-yl](p-tol-yl)methanone.
abstract: In the title compound C18H15ClN2O2, the dihedral angles between the central pyrazole ring and the pendant chloro-benzene and p-tolyl rings are 17.68 (10) and 51.26 (12)°, respectively. An intra-molecular O-H⋯O hydrogen bond is observed, which closes an S(6) ring.
