摘要：

The decatungstomolybdoniobogermanic heteropoly acid H-5[GeW10MoNbO40] (.) 20H(2)O has been prepared for the first time. The optimal proportion of the solutions of the component and the pH of the synthesis reaction are given. The product was characterized by chemical analysis, conductometric and potentiometric titration, IR, UV, XRD, W-183 NMR and TG-DTA. The IR, UV. XRD and W-183 NMR indicate that H-5[GeW10MoNbO40] (.) 20H(2)O. possesses the Keggin structure. The TG-DTA curve shows the sequence of water loss in the acid, the amount of the loss as well as the thermostability of the acid. (C) 2002 Published by Elsevier Science B.V.
