Abstract

Abstract: The substituted tungstosilicate complexes α-Na_mH_n[SiW₉M₃(H₂O)₃O₃₇]·16H₂O (M=Co(Ⅱ), Ni(Ⅱ), V(Ⅴ)) were synthesized and characterized by IR, UV, ICP, TG DTA, EPR and XPS. The conductivity of co complex was above 1×10^-3S/cm at room temperature and 1×10^-2S/cm at 343 K. The magnetic susceptibility data obtained in the range of 75～300.K have fitted with J and g , based on the spin hamiltonian S_j.

Key words: tungstosilicate heteropoly complex, conductivity, magnetic susceptibility
