A host-guest hybrid framework with Anderson anions as template: synthesis, crystal structure and photocatalytic properties

A new Anderson-anion-templated inorganic-organic hybrid compound, H[(bitdc)Ni(H2O)(3)](2)[IMo6O24]center dot 6H(2)O (1) (bitdc = N,N'-bis(isonicotinoyl)-trans-1,2-diaminocyclohexane), has been synthesized and characterized by elemental analysis, IR spectroscopy, TG analysis, Powder XRD and single-crystal X-ray diffraction. Compound 1 is made up of Anderson-type polyoxoanions [IMo6O24](5-) and dinuclear [(bitdc)(2)Ni-2(H2O)(6)](4+) coordination complexes to yield an intriguing 3D supramolecular host-guest structure. To our best knowledge, compound 1 represents the first example of host-guest compounds with Anderson anions as template. The photocatalytic properties and magnetic properties of 1 have been investigated. (C) 2012 Elsevier B.V. All rights reserved.
