title: Bis[μ-2,2'-dimethyl-1,1'-(oxydiethyl-ene)bis-(1H-benzimidazole)-κN:N]bis-[bis-(4-methoxy-benzoato-κO,O')cadmium(II)].
abstract: The title complex, [Cd(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], forms a dimer of the paddle-wheel type, located on a crystallographic inversion centre. The Cd(II) ion is hexa-coordinated by four carboxylate O atoms [Cd⋯O = 2.280 (2)-2.404 (2) Å] from two chelating 4-methoxy-benzoate anions, and two N atoms [Cd⋯N = 2.313 (2) and 2.332 (2) Å] from one chelating 2,2'-dimethyl-3,3'-(oxydiethyl-ene)bis-(1H-benzimidazole) ligand. In the crystal, mol-ecules are linked by a weak inter-molecular C-H⋯O hydrogen bond and an inter-molecular C-H⋯π inter-action.
