Novel tetranuclear mixed-metal complexes containing the heteronuclear ions [MII{(OH)2CrA4}3]5+ and [MII{(OH)2CoA4}3]5+(A = amine ligand)

Abstract

The synthesis and structural characterization of new tetranuclear complex ions with a central bivalent metal ion [Mg^II, Zn^II, Co^II, Mn^II, or Ni^II] octahedrally co-ordinated to six hydroxo groups which act as bridging ligands to three trivalent metal ions [Cr^III or Co^III], is reported.
