Abstract: In the title compound, [CdCl₂(C₁₀H₈N₂)]_n, the Cd^II ion is six-coordinate and has a distorted octahedral geometry. The basal plane is formed by the two N atoms of the 2,2'-bipyridine ligand [Cd-N 2.352  (3)  Å] and two Cl atoms [Cd-Cl 2.5519  (8)  Å]. The apical sites are occupied by Cl atoms from neighbouring monomeric units [Cd-Cl 2.7517  (9)  Å]. All the Cl atoms act as bridging ligands. The adjacent Cd coordination polyhedra share Cl-Cl edges, thus giving rise to a polymeric chain along the c axis. The Cd^II ion is positioned on a twofold axis.
