From the reaction of 1,2-dichlorotetramethyldisilane with tetramethylcyclopentadienyl lithium, 1,2-bis(tetramethylcyclopentadienyl) tetramethyldisilane (1) was formed. 1 was treated with n-butyl lithium and followed by reacting with tiCl4.2THF, the title compound 2 was obtained. Its structure was characterized by elemental analysis, UV, MS, ^1H NMR spectra and determined by X-ray diffraction analysis. The crystal belongs to monoclinic, space group C2/c. The parameters of the crystal are: a=1.5060(3), b=0.9591(2), c=1.7490(3)nm; β=107.91(2)°, V=2.404(2)nm^3, Z=4, Dc=1.314g/cm^3, μ=6.80cm^-^1, F(000)=1008, R=0.047.
