The chain structure ofcatena-poly[[(2,2′-bipyridine)cadmium(II)]-di-μ-chloro

Abstract

In the title compound, [CdCl2(C10H8N2)]n, the CdII 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 CdII ion is positioned on a twofold axis.
