Reactions of (C(5)H(4)SiMe(3))SiMe(2)Cl (1) and (mu-SiMe(2)C(5)H(4))(2) (2) with Ti, Zr and Hf tetrachlorides lead to the complexes M(eta(5)-C(5)H(4)SiMe(2)Cl)Cl-3 (M = Ti, 3a; Zr, 3b; Hf, 3c). Treatment of 3a with cyclopentadienyl thallium affords Ti(eta(5)-C5H5)(eta(5)- C(5)H(4)SiMe(2)Cl)Cl-2 (4). Dimeric oxo-derivative [TiCl2(mu-OSiMe(2)-eta(5)-C5H4)](2) (5) was prepared by slow hydrolysis of 3a. Structure of 5 was determined by X-ray diffraction.
