✦ Synopsis
The title compound, C 13 H 11 Br 3 , has a planar framework of C atoms with no distortion towards helicity. The two adjacent bromine substituents point to opposite sides of the ring system. Two bromine±bromine contacts, with distances less than twice the van der Waals radius, link the molecules to form ribbons parallel to the a axis. Weak CÐHÁ Á ÁBr hydrogen bonds and partial ring stacking complete the crystal packing.

The structure of the title compound, C 22 H 14 Br 2 O 2 reveals the anti conformation of the two naphthalene rings. The plane of the ester group is almost perpendicular to the planes of the two aromatic rings.
We are investigating the structures of 1,8-disubstituted naphthalenes as part of a wider study into steric crowding and hyperconjugation. In the title compound, C 16 H 11 BrSe, the SeÁ Á ÁBr distance is 3.1136 (5) A ˚. The Br and Se atoms lie 0.400 (1) and À0.421 (1) A ˚, respectively, from the mean
