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]·6H2O (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)2Ni2(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.
