Studies on Magnetism and Conductibility of Trisubstituted Tungstogalliumate Containing Transition Metal

合成了过渡金属三取代的钨镓杂多配合物:α-NanHm[GaW_9O_(37)M_3(H_2O)_3]·xH_2O[M=Fe(Ⅲ),Cu(Ⅱ),Co(Ⅱ)].通过元素分析、红外、紫外、^(183)W NMR以及热分析等手段进行了表征,变温磁化率数据显示了配合物具有反铁磁特征.电导率测定结果表明所合成的配合物是迄今未见文献报道的过渡金属三取代杂多配合物高质子导体,室温下GaW_9Fe_3的σ值可达10^(-3)S·cm^(-1),其特点是热稳定范围宽,不易失水,可望成为能实用化的杂多酸型固体电解质.

The trisubstituted tungstogalliumate a-NanHm[GaW9O37M3(H2O)3]·nH2O[M=Fe (III),Cu( II ),Co( II )] have been synthesized and characterized by elemental analysis ,UV, IR, electrochemistry, 183W NMR and TG - DTA. The date of megnetic susceptibility show that complexes possess antiferromagnetism. The determination of conductibility exhibit that complexesare a excellent high - proton conductor. In which, σ value of GaW9Fe3 is above 10-3 S·cm-1 at15℃. The title complexes with high stability to thermal will be expeted to be practical heteropolyacid type solid electrolyte.
