(E)-3-(4-Heptyl­oxyphen­yl)-1-phenyl­prop-2-en-1-one

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 R₂²(8) ring motifs. There are also C—H...π inter­actions present, which link the double-stranded chains, forming a two-dimensional network.
