| Abstract: Reaction of the trivacant heteropolyanions α-A-PW9O349- with CH3SiCl3 leads to the formation of the organosilyl derivative (TBA)3[α-A-PW9O34(CH3SiO)3(CH3Si)]. The crystal X-ray diffraction analysis shows that the crystal belongs to orthorhombic with space group Pca21, M=3177.09 and the unit cell parameters: a=25.761(5)?,b=14.519(3)?,c=24.396(5)?.V=9124(3)?3,Z=4,Dc=2.225g·cm-3,μ(MoKα)=11.438mm-1,F(000)=5464,R=0.0561,Rw=0.0866. The anion consists of one α-A-PW9O349- anion linked by three CH3SiO+ groups, which attached to the fourth CH3Si through three Si-O-Si bridges. |
