Crystal structure of 3-(4-methylphenyl)-1-phenyl-5-[(E)-2-phenylethenyl]-1H-pyrazole

Abstract

In the title compound, C24H20N2, the dihedral angles between the pyrazole ring and the pendant phenyl, toluoyl and phenylethenyl rings are 41.50(8), 4.41(8) and 31.07(8)°, respectively. In the crystal, inversion dimers linked by a π-π stacking interactions between the phenylethenyl rings are observed [centroid-centroid separation = 3.5857(9)Å].
