摘要：
In the title compound, C24H15BrO3, the pyranochromenone ring is essentially planar, while the 2-bromophenyl group is almost perpendicular to it [85.58 (6)degrees]. In the crystal, inversion dimers linked by pairs of weak C-H center dot center dot center dot pi bonds occur; there is also a short interatomic contact found between the Br and carbonyl O atoms [3.016 (1) angstrom].
