Abstract:
In the title compound, C20H21ClN2O, the dihedral angles between the pyrazole ring (r.m.s. deviation = 0.049 Å) and the benzene and chloro-benzene rings are 84.65 (10) and 3.35 (10)°, respectively. In the crystal, inversion dimers linked by pairs of weak C-H⋯O inter-actions generate R 2 (2)(16) loops. Weak π-π stacking inter-actions [centroid-centroid distance = 3.8490 (11) Å] are also observed.
