Trichlorido(tetrahydrofuran){(1,2,3,3a,7a-η)-1-[2-(1-trimethylsilyl-1H-imidazol-2-yl-κN (3))-1-methylpropyl]indenyl}zirconium(IV)
The title compound, [ZrCl(3)(C(19)H(25)N(2)Si)(C(4)H(8)O)], was prepared from bis(N,N-dimethylamido-κN)(2-{2-[(1,2,3,3a,7a-η)-indenyl]-2-methylpropyl}-1H-imidazolido-κN (1))zirconium(IV) [(C(16)H(16)N(2))Zr(NMe(2))] by reaction with excess Me(3)SiCl in tetrahydrofuran (THF) at elevated temper...

Sumario: | The title compound, [ZrCl(3)(C(19)H(25)N(2)Si)(C(4)H(8)O)], was prepared from bis(N,N-dimethylamido-κN)(2-{2-[(1,2,3,3a,7a-η)-indenyl]-2-methylpropyl}-1H-imidazolido-κN (1))zirconium(IV) [(C(16)H(16)N(2))Zr(NMe(2))] by reaction with excess Me(3)SiCl in tetrahydrofuran (THF) at elevated temperature. The crystal studied contained a minor non-merohedral twin contaminant [6.3 (4)%] which was taken into account during the refinement. The coordination polyhedron of the Zr(IV) atom is a distorted octahedron [assuming that the five-membered ring of the indenyl group (Cp) occupies one coordination site], with the Cp group and a THF O atom at the apical positions and the three Cl and ligating N atoms at the equatorial positions. The Zr, Si and the methylene C atoms deviate noticeably from the imidazole ring plane [by −0.197 (5), −0.207 (5) and 0.119 (6) Å, respectively]. The THF ligand adopts an envelope conformation. |
