Abstract: | An undeca-nuclear nickel substituted POM, namely Ni(H(2)O)(6)]Ni(11)(PW(9)O(34))(2)(IDA)(3)(en)(2)(Hen)(2)(OH)(6)]·(H(2)O)(7)·(H(2)en)(2) (1) (en = 1,2-ethylenediamine, H(2)IDA = iminodiacetic acid), was synthesized through hydrothermal reaction of Na(6)PW(9)O(34), en, H(2)IDA and NiCl(2)·6H(2)O. Single-crystal structure reveals that 1 can be viewed as Ni(6)PW(9) and Ni(5)PW(9) units linked by a μ(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. |
