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 Na 2 MoO 4 ·2H 2 O and MoO 3 with MCl 2 ·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 - (H 2 O) y Mo n O 3n +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).
