Solid state coordination chemistry:: construction of 2D networks and 3D frameworks from phosphomolybdate clusters and binuclear Cu(II) complexes.: The syntheses and structures of [{Cu2( tpypyz)(H2O)2}(Mo5O15)(HOPO3)2]•nH2O [n = 2, 3; tpypyz = tetra(2-pyridyl)pyrazine]

The hydrothermal reaction of MoO3, Cu(C2H3O2)(2).H2O, tpypyz, H3PO4 and H2O yields a 2D material, [{Cu-2(tpypyz)(H2O)(2)}(Mo5O15)(HOPO3)(2)]. 2H(2)O (1 . 2H(2)O), constructed from {Mo5O15(HOPO3)(2)}(4-) clusters linked through {Cu-2(tpypyz)(H2O)(2)}(2+) components; in contrast, use of Cu2O in the synthesis in place of Cu(C2H3O2)(2).H2O yields a 3D material [{Cu-2(tpypyz)(H2O)(2)}(Mo5O15)(HOPO3)(2)]. 3H(2)O (2 . 3H(2)O), constructed from the same building blocks as 1 . 2H(2)O.
