Abstract

In the the title compound, C(27)H(23)ClN(4)O(2), the chloro-phenyl 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 mol-ecules 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 inter-actions involving the chloro-phenyl ring.
