5-(2,3-Dichlorophenyl)-3-(4-methoxyphenyl)-1-phenyl-4,5-dihydro-1H-pyrazole

Abstract

In the racemic title compound, C22H18Cl2N2O, the dihedral angles between the central dihydropyrazole ring (r.m.s. deviation = 0.018 Å) and the pendant methoxyphenyl, phenyl and dichlorophenyl rings are 3.96 (9), 15.90 (9) and 66.65 (9)° respectively. Weak aromatic π–π stacking [shortest centroid–centroid separation = 3.8476 (11) Å] occurs in the crystal.
