Poly[diaqua-di--malonato-cobalt(II)disodium(I)]

D.-Q. Wang

Abstract: In the title compound, [CoNa₂(C₃H₂O₄)₂(H₂O)₂]_n, a heterobimetallic malonate complex, both Co^II and Na^I ions have distorted octahedral coordination geometries. The Co^II ions are located on inversion centres and are surrounded only by carboxylate O atoms, while the Na^I ions are coordinated both by water and by carboxylate O atoms. The malonate dianions show an unusual heptadentate bridging mode.
