Abstract
A new crown inorganic-organic hybrid material composed of the Keggin polyoxometalates and transition metal-amino acid coordination complexes, K2{[KCu4(gly)4(OH)2(H2O)2Cl][PW12O40]}2·19H2O (1), was synthesized and characterized by elemental analysis, IR spectroscopy, TG analysis and single crystal X-ray diffraction. Compound 1 possesses of a 1D chain structure with a crown-type monomer, which is built up from [PW12O40]3- building blocks and tetranuclear [KCu4(gly)4(OH)2(H2O)2Cl] rings. The [KCu4(gly)4(OH)2(H2O)2Cl] ring consists of four Cu2+ ions and four gly ligands, which exhibits the crown ether feature binding a potassium ion in its center. Further, two [KCu4(gly)4(OH)2(H2O)2Cl] rings linked two Keggin polyoxoanions [PW12O40]3- into crown inorganic-organic hybrid material. Magnetic study shows the existence of ferromagnetic interactions in compound 1.
