RESUMEN
In the title compound C27H22Cl2N4O2, the pyrazol-5-ol ring makes a dihedral angle of 34.80â (11)° with the phenyl ring to which it is bound, while the pyrazolone ring is inclined at 34.34â (12)° to its attached phenyl ring. In the crystal, N-Hâ¯O and C-Hâ¯Cl hydrogen bonds link the mol-ecules into chains along [010]. Inter-molecular π-π inter-actions are observed between the pyrazolone ring and the phenyl ring bound to the pyrazol-5-ol ring system [centroid-centroid separation = 3.916â (2)â Å].
