Abstract :
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.
