A functionalized polyoxometalate by hexanuclear copper-amino acid coordination complexes

摘要

A new functionalized polyoxometalate by transition metal-amino acid coordination complexes,H4[Na(H2O)2][Cu6Na(gly)8(H2O)2][BW12O40]2 centre dot 13H2O(1)(gly = glycine)has been synthesized and characterized by elemental analysis,IR spectroscopy,TG analysis,and single crystal X-ray diffraction.Compound 1 possesses a 3D framework,which is built up of [BW12O40]~(5-)building blocks,hexanuclear [Cu6Na(gly)8] coordination clusters and Na+ ions.Furthermore,magnetic measurements show ferromagnetic interactions for compound 1.
