Abstract
X-ray crystal strucrute determination of (cyclopentadienyl)[(1,2,3,4,5-hapto)-4-ferrocenyl-1,2,5,6-tetrakis(trimethylsilyl)cyclohexa-2,4-dien-1-yl] titanium(II). The title compound, (η(5)-cyclopentadienyl)[(1,2,3,4,5-eta.)-4-ferrocenyl-1,2,5,6-tetrakis(trimethylsilyl)cyclohexa-2,4-dien- 1-yl]titanium(II), [TiFe(C5H5)(2)(C23H42Si4)] or [Ti{η(5)-C-6 H-2{Fe(η(5)-C5H4)(η(5)-C5H5)}{Si(CH3)(3)}(4)}(η(5)-C5H5)], possesses two directly linked metallocene units that subtend an angle of 52.9 (1)degrees (defined by the least-squares planes of the directly connected pi -ligands) associated with the steric requirements of the bulky trimethylsilyl substituents.
The cyclohexadienyl ligand adopts an envelope conformation; the perpendicular distance of its η(5)-plane to the Ti atom is 1.512 (1) Angstrom.
