Assembly of a Heteronuclear POM {K5Na6CuⅡ5(CH3COO)20(CH3CN)Cl}n via Two Kinds of Clusters as the Basic Bridge Unit

摘要

A novel 3D hetero-nuclear framework,namely [K5Na6CuⅡ5(CH3COO)20(CH3CN)]Cl}n (1),was obtained by hydrothermal reaction.Triple metal centers (including sodium/potassium or/and copper) were coordinated to acetate anions in such two heteronuclear clusters,respectively.Moreover,nine kinds of binding modes for acetate anions were illustrated in polymer 1,with the first reported pentadentate coordination mode for acetate ligand.
