The hydrothermal syntheses and characterization of one- and two-dimensional structures constructed from metal-organic derivatives of polyoxometalates:: [{Cu(bpy)2}{Cu(bpy)(H2O)}(Mo5O15){O3P(CH2)4PO3}]•H2O and [{Cu2(tpypyz)(H2O)2}(Mo5O15)(O3PCH2CH2PO3)]•5.5H2O [bpy=2,2′-bipyridine, tpypyz = tetra(2-pyridyl)pyrazine]

The hydrothermal reaction Of CuSO4. 5H(2)O, Na2MoO4. 2H(2)O and 2,2'-bipyridine with the bridging diphosphonate ligand H2O3P(CH2)(4)PO3H2 yields the one-dimensional chain [{Cu(bPY)(2)}{Cu(bPY)(H2O)(2)}(Mo5O15){O3P(CH2)(4)PO3}].H2O; the introduction of a second bridging component in the reaction of Cu(MeCO2)(2).H2O, MoO3, H2O3PCH2CH2PO3H2 and tetra(2-pyridyl)pyrazine yields the network solid [{Cu-2(tpypyz)(H2O)(2)}(Mo5O15)(O3PCH2CH2PO3)].5.5H(2)O.
