چکیده
In the title coordination polymer, [CdBr(2)(C(8)H(8)N(2)S(2))](n), the Cd(II) atom is six-coordinated in a distorted octa-hedral geometry by two N atoms from a 2,2'-dimethyl-4,4'-bi-1,3-thia-zole ligand and four bridging Br atoms. The bridging function of the Br atoms leads to a chain structure along [100]. Inter-chain C-H⋯Br hydrogen bonds and π-π contacts between the thia-zole rings [centroid-centroid distances = 3.810 (5) and 3.679 (5) Å] are observed.
