Bis[μ-2,2′-dimethyl-1,1′-(oxydiethyl­ene)bis­(1H-benzimidazole)-κ(2) N (3):N (3′)]bis­[bis­(4-methoxy­benzoato-κ(2) O,O′)cadmium(II)]

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 hexa­coordinated by four carboxylate O atoms [Cd⋯O = 2.280 (2)–2.404 (2) Å] from two chelating 4-methoxy­benzoate anions, and two N atoms [Cd⋯N = 2.313 (2) and 2.332 (2) Å] from one chelating 2,2′-dimethyl-3,3′-(oxydiethyl­ene)bis­(1H-benzimidazole) ligand. In the crystal, mol­ecules are linked by a weak inter­molecular C—H⋯O hydrogen bond and an inter­molecular C—H⋯π inter­action.
