摘要
本文合成了钒取代的一系列钨镓杂多酸盐M_(5+)[GaV_xW_(12-x)O_(40)]nHO_2(M=K^+,NH_4^+,Me_4N^+,Et_4N^+,Bu_4N^+,H;X=1,2,3,4),用IR、UV光谱,^(51)VNMR谱、极谱和循环伏安及X射线粉末衍射等方法进行了表征。试验了这些化合物在水溶液中的稳定性和热稳定性。
A series of heteropoly compounds M_(5+x)[GaV_xW_(12-x)O_(40)]·XH_2O(M=K, H, NH_4. Me_4N, Et_4N, Bu_4 N;x =1, 2, 3, 4)were prepared and characterized by IR,UV, ^(51)V NMR spectra,X—ray powder diffraction and polarography. Their stability in water and thermal stability were determined.
