4-(2-Bromophenyl)-2-phenylpyrano[3,2-c]chromen-5(4H)-one

M. Gohain, N. Loganathan, B. C. B. Bezuidenhoudt and A. Roodt

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