| Abstract: A methylphenylsilyl group-substituted derivative [(C4H9)4N]3[α-A-PW9O34(C6H5SiCH3)3](1) has been obtained by reaction of the trivacant [α-A-PW9O34]9- anion with dichloromethylphenylsilane C6H5SiCH3Cl2 in acetonitrile. The new complex was characterized by elemental analysis, IR spectra, UV spectra, thermogravimetric analysis and X-ray crystallography. The compound 1 crystallizes in the trigonal space group R3m, with lattice constants a=2.261 3(2) nm, b=2.261 3(2) nm, c=1.797 6(4) nm, V=7.960 2(18) nm3, and Z=3. The polyoxoanion [α-A-PW9O34(C6H5SiCH3)3]3- has a structure of virtual C3v symmetry with three C6H5SiCH3 groups grafted on the surface of the trivacant tungstophosphate and displays an “open-structure”.
