title: Crystal structure of 1-{3-(4-methyl-phen-yl)-5-[(E)-2-phenyl-ethen-yl]-4,5-di-hydro-1H-pyrazol-1-yl}ethan-1-one.
abstract: The title compound, C20H20N2O, was studied as a part of our work on pyrazoline derivatives. It represents a trans-isomer. The central pyrazoline ring adopts an envelope conformation with the asymmetric C atom having the largest deviation of 0.107 (1) Å from the mean plane. It forms dihedral angles of 6.2 (1) and 86.4 (1)° with the adjacent p-tolyl and styrene groups, respectively. In the crystal, C-H⋯O inter-actions link mol-ecules into infinite chains along the c axis.
