The structure of the title compound, C16H14O2, features a dihedral angle of 54.4 (3)° between the aromatic rings. The allyl group is rotated by 37.4 (4)° relative to the adjacent benzene ring. The crystal packing is characterized by numerous C-H⋯O and C-H⋯π inter-actions. Most of these inter-actions occur in layers along (011). The layers are linked by C-H⋯π inter-actions along [100], forming a three-dimensional network.
