Combination between lacunary polyoxometalates and high-nuclear transition metal clusters under hydrothermal conditions: I. from isolated cluster to 1-D chain

The hydrothermal reactions of A-alpha-SiW(9)O(34)(10-)/A-alpha-PW(9)O(34)(9-) with NiCl(2) x 6H(2)O and amines yielded four unprecedented hybrid high-nuclear Ni-subsituted polyoxotungstates.
