Ethyl 3-(4-chlorophenyl)-1-(2-oxo-2-phenylethyl)-1H-pyrazole-5-carboxylate

In the title compound, C20H17ClN2O3, the dihedral angles between the pyrazole ring and the substituted and unsubstituted benzene rings are 3.64 (13) and 81.15 (17)°, respectively. Molecules are connected via three pairs of weak hydrogen bonds into a centrosymmetric dimer...

Description
Summary:In the title compound, C20H17ClN2O3, the dihedral angles between the pyrazole ring and the substituted and unsubstituted benzene rings are 3.64 (13) and 81.15 (17)°, respectively. Molecules are connected via three pairs of weak hydrogen bonds into a centrosymmetric dimer. The crystal structure is stabilized by intermolecular C—H...O and C—H...π interactions.
