A new polyoxometalate-based inorganic-organic hybrid compound [(NH3C6H4)2SO2]2SiMo12O40·2CH3CN·CH3OH·2H2O has been synthesized and characterized by IR, UV, elemental analysis, and X-ray crystallography. [(NH3C6H4)2SO2]2+ cation balances the charge on the α-Keggin [SiMo12O40]4- anion. The cooperativity of intermolecular N−H···N, N−H···O, O−H···N and C−H···O hydrogen bonds link the subunits together to form a three-dimensional supramolecular framework. The luminescent properties of the title compound at room temperature were investigated. [ABSTRACT FROM AUTHOR]

Abstract: The polyoxometalate-based 1D coordination polymer [Cu(DMF)6][PMoVMoVI 11O40Cu(DMF)4]·DMF 1 was synthesized and characterized by IR, UV spectroscopy and single-crystal X-ray diffraction analysis. Each Cu(II) center has a distorted octahedral coordination geometry. Cu(1) center interconnects with two [PMoVMoVI 11O40]4− anion subunits and each [PMoVMoVI 11O40]4− polyoxoanion acts as a didentate ligand to link two Cu centers through two terminal oxygen atoms to form a one-dimensional chain structure. The luminescent properties of 1 in the solution and in the solid state were investigated, respectively. [ABSTRACT FROM AUTHOR]
