Abstract: The title compound, C19H18O3, crystallizes with three mol­ecules (A, B and C) in the asymmetric unit. The carbonyl O atom shows positional disorder over two sites in mol­ecules A and B; the site-occupancy ratios are 0.76 (3):0.24 (3) and 0.86 (3):0.14 (3), respectively. The ethyl­ene fragments in each mol­ecule have an E conformation, while the C-O-C-C torsion angles indicate near planarity. The dihedral angles formed by the aromatic rings are 20.0 (1), 23.7 (1) and 16.1 (1)° for mol­ecules A, B and C, respectively. Intra­molecular C-H...O hydrogen bonds occur in each mol­ecule.
