title: Ethyl 3-(4-chloro-phen-yl)-1-(2-oxo-2-phenyl-eth-yl)-1H-pyrazole-5-carboxyl-ate.
abstract: In the title compound, C(20)H(17)ClN(2)O(3), the dihedral angles between the pyrazole ring and the substituted and unsubstituted benzene rings are 3.64 (13) and 81.15 (17)°, respectively. Mol-ecules are connected via three pairs of weak hydrogen bonds into a centrosymmetric dimer. The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions.
