摘要: 合成了α-NamHn[SiW9M3(H2O)3O37]·16H2O(M=Co(Ⅱ),Ni(Ⅱ),V(Ⅴ)杂多配合物),通过ICP,IR,UV,TG-DTA,XPS,EPR,极谱等手段进行了表征。配合物在室温下的电导率σ值达1×10-3S·cm-1,343K时可达1×10-2S·cm-1,是有实用化前景的新型固体电解质。变温磁化率结果表明α-Na10[SiW9Co3(H2O)3O37]·16H2O和α-Na10[SiW9Ni3(H2O)3O37]·16H2O具有反铁磁性。

Abstract: The substituted tungstosilicate complexes α-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 1×10-3S/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 Sj.

Key words: tungstosilicate heteropoly complex, conductivity, magnetic susceptibility
