4-(4-Chloro­phen­yl)(5-hydr­oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)meth­yl-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one

摘要

In the the title compound, C27H23ClN4O2, the chloro­phenyl ring forms dihedral angles of 77.70 (9) and 86.65 (9)°, respectively, with the pyrazol-3-one and pyrazole rings. The phenyl rings attached to the pyrazole rings are twisted away from them [dihedral angles 33.80 (9) and 40.34 (10)°]. An intramolecular O—H⋯O hydrogen bond generates an S(8) ring motif. The mol­ecules are linked into chains running along the c axis by N—H⋯N hydrogen bonds, and the chains are cross-linked via C—H⋯O hydrogen bonds and C—H⋯π inter­actions involving the chloro­phenyl ring.
