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".CCDC:830334.
