| Abstract: | Reaction of the trivacant heteropolyanions α-A-PW 9O 34 9- with Ph 2SiCl 2 leads to the formation of the diphenylsilicion derivatives (TBA) 3α-A-PW 9O 34 (Ph 2Si) 3]. The complex has been characterized by elemental analysis, IR and UV spectroscopy. The results reveal the fact that the title heteropolyanion consists of one α-PW 9O 34 9- framework on which are grafted by three Ph 2Si groups through six Si-O-W bridges and the heteropolyanion becomes saturated open cage structure. Thermal analysis illustrates that the complex decomposes at the temperature of ca 495.2℃. |
