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—Hπ bonds occur; there is also a short interatomic contact found between the Br and carbonyl O atoms [3.016 (1) Å].

In the title molecule, C16H28O2S, the two n-hexyl groups are in all-trans conformations. Their C atoms are situated close to the plane of the thiophene ring with a maximum deviation of 0.718 (6) Å for one of the terminal methyl groups. In the crystal, a short C—HO contact is observed between thiophene 1,1-dioxide groups.
