Crystal structures of two ansa-titanocene tri­fluoro­methane­sulfonate complexes bearing the Me(2)Si(C(5)Me(4))(2) ligand

The crystal structures of two ansa-titanocene tri­fluoro­methane­sulfonate complexes bearing the Me(2)Si(C(5)Me(4))(2) ligand are reported, namely [di­methylbis­(η(5)-tetra­methyl­cyclo­penta­dien­yl)silane](tri­fluoro­methane­sulfonato-κ(2) O,O′)titanium(III) toluene monosolvate, [Ti(CF(3)O(3)S)(C(...

Sumario:The crystal structures of two ansa-titanocene tri­fluoro­methane­sulfonate complexes bearing the Me(2)Si(C(5)Me(4))(2) ligand are reported, namely [di­methylbis­(η(5)-tetra­methyl­cyclo­penta­dien­yl)silane](tri­fluoro­methane­sulfonato-κ(2) O,O′)titanium(III) toluene monosolvate, [Ti(CF(3)O(3)S)(C(20)H(30)Si)]·C(7)H(8), 1, and chlorido­[di­methyl­bis­(η(5)-tetra­methyl­cyclo­penta­dien­yl)silane](tri­fluoro­methane­sulfonato-κO)titanium(IV), [Ti(CF(3)O(3)S)(C(20)H(30)Si)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.
