catena-Poly[[(acetato-κO,O')(methanol-κO)cadmium(II)]-μ-[1,2-bis-(1H-benzimid-azol-2-yl)ethane]-κN:N-[(acetato-κO,O')(methanol-κO)cadmium(II)]-di-μ-chlorido].

In the title complex, [Cd(2)(CH(3)COO)(2)Cl(2)(C(16)H(14)N(4))(CH(3)OH)(2)](n), the Cd(II) atom is six-coordinated by one N atom from a centrosymmetric bridging 1,2-bis-(2,2'-1H-benzimidazol-2-yl)ethane (bbe) ligand, two O atoms from a chelating acetate ligand, one O atom from a methanol mol-ecule and two bridging Cl atoms in a distorted octa-hedral geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bbe ligands, leading to a chain along [001]. These chains are further linked by O-H⋯O hydrogen bonds. Intra-chain N-H⋯O hydrogen bonds are observed.
