1-[5-(2-Chloro­phen­yl)-3-(4-methyl­phen­yl)-4,5-di­hydro-1H-pyrazol-1-yl]ethan-1-one

The title compound, C18H17ClN2O, crystallized with two independent mol­ecules (the S and R enanti­omers) in the asymmetric unit. The mol­ecules are V-shaped with the two aromatic rings inclined to one another by 78.78 (11) and 81.23 (11)°. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds, forming chains along the c-axis direction. The chains are linked via C—H⋯π inter­actions, forming a three-dimensional framework. The crystal structure was refined as a two-component twin.
