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．

The substituted tungstosilicate complexes αNamHn[SiW9M3(H2O)3O37]·16H2O (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∑i>j=1Jij·Si·Sj. 
