Synthesis and Molecular Structure of [1,3-(Me3Si)2C5H3](Me3SiC5H4)ZrCl2.The unsymmetrically substituted zirconocene dichloride was prepared by reaction of trimethylsilylcyclopentadienyl lithium and 1,3-bis(trimethylsilyl)cyclopentadienyl lithium with ZrCl4 · 2 THF. The molecular structure was determined (P21/a; a = 1 357.9, b = 1 900.0, c = 1 043.2 pm, β = 105,16°). The Zr—Cl distance are remarkably short.
Notes:
Das unsymmetrisch substituierte Zirconocendichlorid entsteht aus (Trimethylsilyl-cyclopentadienyl)lithium und 1,3-[Bis(trimethylsilyl)cyclopentadienyl]lithium mit ZrCl4 · 2 THF. Die Molekülstruktur wurde ermittelt (P21/a; a = 1 357,9, b = 1 900,0, c = 1 043,2 pm, β = 105,16°), auffallend sind kurze Zr—Cl-Abstände.
