The crystal structure of the title compound, C17H10O3, is the first example of a furocoumarin containing three fused rings. The tricyclic furocoumarin fragment is perfectly planar. The phenyl substituent forms a dihedral angle of 39.52 (8)° with the plane of the tricyclic system. The crystal packing involves centrosymmetric dimers interconnected by strong π-interactions between their furo[3,2-c]coumarin fragments [at distances of 3.42 (4) Å].
