Molecules of the title compound, C 8 H 10 Br 2 O 4 , located on symmetry centers, are in a rigid chair conformation, with the COOH and Br substituents axial and equatorial, respectively. The carboxylic acid groups form hydrogen bonds, in a cyclic motif, leading to in®nite chains along the b axis.

## Abstract The homopolyester of isosorbide and __cis__–__trans__ 1,4‐cyclohexane dicarboxylic acid (CHDA) was prepared by three different methods, but only polycondensation of isosorbide and CHDA dichloride yielded a satisfactory molecular weight (corrected $\overline M \_{\rm n} $ = 11 000 Da). F
