Conductivity and Magnetic Property of Substituted Tungstosilicate Heteropoly Complexes
Abstract:
The substituted tungstosilicate complexes T-NamHn[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 1×10-3 S/cm at room temperature and 1×10-2 S/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 H=-2
