1-Acetyl-3-(2,5-dichlorophenyl)-5-(4-fluorophenyl)-2-pyrazoline

Abstract

The title compound, C17H13Cl2FN2O, was prepared by the reaction of hydrazine and 1-(2,5-dichloro­phenyl)-3-(4-fluoro­phenyl)-2-propenyl-1-ketone. In the mol­ecule, the dihedral angle between the two benzene rings is 66.63 (9)°. In the crystal structure, weak inter­molecular C—H⋯Cl hydrogen bonds connect mol­ecules into centrosymmetric dimers.
