The title compound, C23H16O, has two independent molecules in the asymmetric unit. The bond lengths and angles of the two molecules are identical. The conformation of the isobenzofuran ring systems of the molecules, however, differ slightly; in molecule A, the sp2-C atom of the five-membered ring deviates the greatest distance [0.034(2)A] from the benzo plane, while in molecule B, it is the sp3-C atom of the five-membered ring which has the greatest deviation [0.027(2)A] from the benzo plane.
