✦ Synopsis

The molecule of the title compound, C 21 H 22 N 2 O 2 , is nearly planar, except for the C(CH 3 ) 2 group on the cyclohexene ring. Molecules are connected via electrostatic CÁ Á ÁO contacts, forming zigzag pseudo-chains along the c axis.

At 150 K, the tricyclic core of the title compound, C 34 H 31 NO 3 , is close to planar. One of the three 4-methoxyphenyl substituents is twisted out of the plane of the tricyclic core due to steric congestion.
