Abstract

Abstract The reaction of [Cp 2 TiCl 2 ] with E(SiMe 3 ) 2 leads to dinuclear Ti complexes. In [Cp 3 Ti 2 S 2 Cl] (1) and [Cp 3 Ti 2 Se 2 Cl] (3) two μ 2 -S(Se) ligands bridge the Cp 2 Ti and CpTiCl units, respectively in contrast to these, [Cp 4 Ti 2 S 2 Cl 2 ] (2) contains a μ 2 η 1 -S 2 bridge connecting two Cp 2 TiCl fragments. A similar reaction of [CpTiCl 3 ] with Se(SiMe 3 ) 2 leads to the tetranuclear cluster [Cp 4 Ti 4 Se 7 O] (4). 4 consists of a Ti 4 -tetrahedron which encloses an oxygen atom.
