The substituted tungstosilicate complexes α -Na n SiW 9M 3(H 2O) 3O 37 ·18H 2O and α -Na n SiW 9M 3(H 2O) 3O 39 ·18H 2O were synthesized and characterized. The conductivity of α -SiW 9Fe 3 was above 10 -3 S·cm -1 at room temperature and 1×10 -2 S·cm -1 at 343 K.The determination of conductivity exhibits that the complxes are an excellent high-proton conductor. The magnetic susceptibility data obtained. α -SiW 9M 3 have magnetic properties.
