The reaction of [Cp2TiCl2 ] with E(SiMe3)2 leads to dinuclear Ti complexes. In [Cp3Ti2S2Cl] (1) and [Cp3Ti2Se2Cl] (3) two μ2 -S(Se) ligands bridge the Cp2Ti and CpTiCl units, respectively in contrast to these, [Cp4Ti2S2Cl2] (2) contains a μ2η1-S2 bridge connecting two Cp2TiCl fragments. A similar reaction of [CpTiCl3] with Se(SiMe3)2 leads to the tetranuclear cluster [Cp4Ti4Se7O] (4). 4 consists of a Ti4 -tetrahedron which encloses an oxygen atom.
