A inorganic-organic hybrid material constructed from the monolacunary polyoxomolybdates and multi-nuclear copper clusters

A novel polyoxometalate (POM)-based inorganic-organic hybrid material constructed from the monolacunary Keggin-type polyoxomolybdates and the multi-nuclear copper clusters, namely, {[Cu-8(tz)(8)(Htz)(4)(H2O)(5)][(PMo10MoO39)-Mo-VI-O-V]} center dot 10H(2)O (1) (Htz = 1H-tetrazole) has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, IR spectra, PXRD analysis. In 1, the six-nuclear copper clusters in the roof shape were bridged by the tz ligands. These clusters are extended into the wave-like layers by the mu(2)-Htz ligands and the copper atoms in octahedron coordination geometry. The polyoxomolybdate anions act as the eight-connected node to link the layers into a 3D framework. In addition, the magnetic and photocatalytic properties of compound 1 have been investigated.
