Trichlorido{2-[2-(η-cyclo-penta-dien-yl)-2-methyl-prop-yl]-1-trimethyl-silyl-1H-imidazole-κN}titanium(IV) tetra-hydro-furan hemisolvate.

ABSTRACT: The title compound, [Ti(C(15)H(23)N(2)Si)Cl(3)]·0.5C(4)H(8)O, has been prepared from {2-[2-(η(5)-cyclo-penta-dien-yl)-2-methyl-prop-yl]-1H-imidazolyl-κN(1)}bis-(N,N-diethyl-amido-κN)titanium(IV), (C(12)H(14)N(2))Ti(NEt(2))(2), by reaction with excess of Me(3)SiCl in tetra-hydro-furan (THF) at 353 K. The crystal structure contains THF as adduct solvent, disordered around a center of inversion. The presence of THF and the adduct ratio has been independently supported by (1)H NMR spectroscopy. The coordination polyhedron of the Ti atom is distorted square-pyramidal, assuming the cyclo-penta-dienyl (Cp) ring occupies one coordination site. The Ti, Si and CH(2) group C atoms only deviate slightly from the imidazole ring plane [by 0.021 (4), 0.133 (4) and 0.094 (4) Å, respectively]. Comparison o
