A one-dimensional polyoxometalate-based polymer [Cu(DMF)6][PMoVMoVI11O40Cu(DMF)4]·DMF: Crystal structure and luminescent properties

The polyoxometalate-based 1D coordination polymer [Cu(DMF)6][PMoVMoVI11O40Cu(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 [PMoVMoVI11O40]4− anion subunits and each [PMoVMoVI11O40]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.
