Abstract

A series of new half-sandwich vanadium complexes have been prepared. The structures of two new anionic vanadium half-sandwich complexes, CpVCl(3) and CpV(N)Cl(2) are presented. (15)N isotopic labelling studies have been conducted to unambiguously assign the V[triple bond, length as m-dash]N infra red stretching frequencies of both a neutral and an anionic (cyclopentadienyl)vanadium nitrido complex. The influence of strongly pi-basic coligands on the hapticity of the cyclopentadienyl ligands in half-sandwich complexes of vanadium is discussed.

摘要

已经制备了一系列新型的半夹心钒配合物。本文呈现了两个新型的阴离子钒半夹心配合物CpVCl(3)和CpV(N)Cl(2)的结构。通过(15)N 同位素标记研究，明确了中性和阴离子（环戊二烯基）钒亚硝酰配合物的 V[三键，长度为 m-dash]N 红外伸缩频率。讨论了强π-碱性配位体对半夹心钒配合物中环戊二烯基配体的亲核性的影响。
