| description | 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) A ° 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 interactions link
molecules into infinite chains along the c axis. |
