1-3,5-Bis(4-chloro{\-}phen{\-}yl)-4,5-dihydro-1{\it H}-pyrazol-1-ylethanone

In the title compound, C\sb 17H\sb 14Cl\sb 2N\sb 2O, the dihedral angles between the pyrazole ring and the mean planes of the benzene and chloro-substituted benzene rings are 75.97(1) and 16.63(1)\circ respectively. In the crystal, two weak C—-H⋅sO inter\-molecular hydrogen bonds and π—π stacking inter\-actions centroid{--}centroid distances = 3.774(4) and 3.716(7){\AA} are observed
