In the crystal of the title polymeric compound, [CdBr2(C12H12N2)]n, the CdII cation is located on a twofold rotation axis and is six-coordinated in a distorted octahedral geometry formed by two N atoms from the 4,4′-dimethyl-2,2′-bipyridine ligand and by four bridging Br− anions. The bridging function of the Br− anions leads to a polymeric chain running along the c axis. Weak C—H⋯π interactions observed between adjacent chains are effective in the stabilization of the three-dimensional packing.
