Abstract:
In the title compound, C21H23ClN2O, the dihedral angle between the benzene rings is 83.2 (6)°, while the mean plane of the pyrazole ring [r.m.s. deviation = 0.043 (1) Å] makes dihedral angles of 3.4 (3) and 86.2 (1)° with the benzene rings. In the crystal, a pair of weak C-H⋯O inter-actions between the benzene ring and the propan-1-one group link the mol-ecules into an inversion dimer with an R 2 (2)(16) graph-set motif. In addition, a weak π-π stacking inter-action [centroid-centroid distance = 3.959 (4) Å] connects the dimers into a tape running along [201].
