Studies on the Conductivity and Magnetic Properties of Substituted Heteropoly Tungstogallates

合成了过渡金属取代的钨镓杂多配合物α－Na7[GaW11Co（H2O）O39]·16H2O（简写为GaW11Co，其它类同）、α－Na7H2[GaW10Co2（H2O）2O39]·16H2O和α－NanHm[GaW9M3（H2O）3O37]·16H2O[M＝Co（Ⅱ），Ni（Ⅱ），V（Ⅴ）]，通过红外、紫外、ICP、TG－DTA、EPR、XPS、183WNMR、极谱等手段进行了表征．在室温下，α－GaW9Co3的电导率。值可达10－3S·cm－1，343K时可达10-2S·cm-1，表明是一类新型高质子导体．磁分析表明，GaW11Co、GaW9V3具有顺磁性，GaW9Ni3具有反铁磁性．

Five substituted tungstogallate complexes were synthesized and characterized by IR, UV, ICP, TG-DTA, 183W NMR, EPR, XPS. The determination of conductivity ex-hibits that the complexes are an excellent high-proton conductor. In which, d value of GaW9Co3 is above 10-3 S. cm-1 at room temperature and 10-2 S. cm-1 at 343 K. The mag-netic susceptibility data obtained in the range of 75-300 K have been fitted with J and g,based on the spin Hamiltonian H
