Synthese und struktur von dicyclopentadienyl(trimethylsilyl)titanchlorid

Abstract Dicyclopentadienyl(trimethylsilyl)titanium chloride, a stable trimethylsilyltitanium compound, is synthesized by reaction of dicyclopentadienyltitanium dichloride and tris(trimethylsilyl)aluminium, coordinated with diethyl ether, or lithium tetarakis(trimethylsilyl)aluminate. The IR and NMR spectra are reported. The crystal structure of the title compound has been determined. It shows a distorted tetrahedral surrounding of the titanium atom; the Ti–Si distance is 267 pm.

Planare Iridium(I)-komplexe mit Tri-t-butylphosphin als Liganden

Abstract Tricarbonylchloroiridium reacts with tri-t-butylphosphine under formation of dicarbonylchloro(tri-t-butylphosphine)iridium (I) and carbonylchlorobis(tri-t-butylphosphine) iridium (II). The crystal structure of I has been determined from single crystal X-ray data. The compound crystallizes with 4 molecules in a unit cell of symmetry P 2 1 / n in the monoclinic system.
