2D and 3D Polymeric Wells-Dawson Polyoxometelates: Synthesis, Crystal Structures, and Cyclic Voltammetry of [(M(H2O)(4))(x)][H6-2xP2W18-nMOnO62] (M = Cu-II, Co-II, Ni-II)
Opposite vertices versus edge Mo ion substitution modes are observed in Wells-Dawson polyanions. The connections of these units by 3d transition metals yield 2D and 3D polymeric materials.
