An undeca-nuclear nickel substituted POM, namely [Ni-(H2O)(6)][Ni-11(PW9O34)(2)(IDA)(3)(en)(2)(Hen)(2)(OH)(6)]center dot(H2O)(7)center dot(H(2)en)(2) (1) (en = 1,2-ethylenediamine, H(2)IDA = iminodiacetic acid), was synthesized through hydrothermal reaction of Na-6-PW9O34, en, H(2)IDA and NiCl2 center dot 6H(2)O. Single-crystal structure reveals that 1 can be viewed as Ni6PW9 and Ni5PW9 units linked by a mu(3)-O bridge and two IDA(2-) ligands. Magnetic investigation indicates the presence of dominantly ferrimagnetic interactions within the Ni-11 core. Electrochemistry study shows that 1 displays a stable and reproducible voltammetric graph.
