【 摘 要 】

The crystal structures of two ansa-titanocene tri­fluoro­methane­sulfonate complexes bearing the Me2Si(C5Me4)2 ligand are reported, namely [di­methylbis­(η5-tetra­methyl­cyclo­penta­dien­yl)silane](tri­fluoro­methane­sulfonato-κ2O,O′)titanium(III) toluene monosolvate, [Ti(CF3O3S)(C20H30Si)]·C7H8, 1, and chlorido­[di­methyl­bis­(η5-tetra­methyl­cyclo­penta­dien­yl)silane](tri­fluoro­methane­sulfonato-κO)titanium(IV), [Ti(CF3O3S)(C20H30Si)Cl], 2. Both complexes display a bent metallocene unit, the metal atom being coordinated in a distorted tetra­hedral geometry, with the tri­fluoro­methane­sulfonate anion acting as a bidentate or monodentate ligand in 1 and 2, respectively. In 1, weak π–π stacking inter­actions involving the toluene solvent mol­ecules [centroid-to-centroid distance = 3.9491 (11) Å] are observed.
