Crystal structure of 4-[(2,4-di­chloro­phen­yl)(5-hy­droxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)meth­yl]-5-methyl-2-phenyl-2,3-di­hydro-1H-pyrazol-3-one

In the title compound C(27)H(22)Cl(2)N(4)O(2), the pyrazol-5-ol ring makes a dihedral angle of 34.80 (11)° with the phenyl ring to which it is bound, while the pyrazolone ring is inclined at 34.34 (12)° to its attached phenyl ring. In the crystal, N—H⋯O and C—H⋯Cl hydrogen bonds link the mol­ecules into chains along [010]. Inter­molecular π–π inter­actions are observed between the pyrazolone ring and the phenyl ring bound to the pyrazol-5-ol ring system [centroid–centroid separation = 3.916 (2) Å].
