One- and two-dimensional organic-inorganic composite solids constructed from molybdenum oxide clusters and chains linked through {M(2,2'-bpy)}(2+) fragments (M=Co, Ni, Cu)

Hydrothermal reactions of Na2MoO4 . 2H(2)O and MoO3 with MCl2 . xH(2)O(M = Co, Ni, Cu) and 2,2'-bipyridine yield one- and two-dimensional solids, characterized by molybdenum oxide monomers, clusters and chains linked by {M(2,2-bpy)}(2+) groups and represented by the formulae [M(bpy)(x)-(H2O)(y)MOnO3n+1] (n = 2, M = Cu, x = 1, y = 0; n = 3, M = Co, x = 1, y = 0; n = 4, M = Ni,x = 2, y = 0).
