Abstract
In the title compound, C22H26O2, the aromatic rings are inclined to one another by 8.39 (9)° and the molecule has an E conformation about the C=C bond. In the crystal, molecules stack head-to-tail along the b-axis direction. They are linked by very weak C—H⋯O contacts, forming C(4) chains along [100]. Two chains are linked by a pair of very weak C—H⋯O contacts, enclosing inversion-dimeric R 2 2(8) ring motifs. There are also C—H⋯π interactions present, which link the double-stranded chains, forming a two-dimensional network.
