1-Indenyl disilane and disiloxane were synthesized by the reaction of indenyl anion with chloropenbtamethyl disilane, 1,2-dichlorotetramethyl disilane and 1,3-dichlorotetramethyl disiloxane respectively. their sturctures were characterized by elemental analyses, UV, IR, 1H NMR and MN, the crystal and molecular structures of 1,2-di (1-indenyl) tetramethy disilane were confirmed by single crystal X-ray diffraction analysis.the crystal belongs to monoclinic , cpace group P21/C, with a=0.7462(2), b=1.4439(3), c=0.9789(2)nm; β=108.12(2)° .V=1.00233nm3, Z=2, Dc=1.14g.cm^-3.R factor is 0.047, Rw is 0.049.The relationship between spectral propertics and molecular structures was disussed.
