1″-terphenyl and nickelocene in which bisnickelacyclic–dilithium complex was formed. It represented the contact ion pair that consisted of nickelacyclic dianion (the first of it's kind) and lithium cations. Exchange of solvent from diethyl ether to DME (1,2-dimethoxyethane) afforded solvent separated ionic pair. Both of these complexes exhibited paramagnetic behaviour, so structural investigations had to be carried
在本文中,我们提出了新颖的双双镍环配合物的合成与表征。我们进行了2,2',2'',5'-四硫代-1,1',4',1''-三苯基与二茂镍之间的反应,其中形成了双镍环-二锂配合物。它是由镍环二价阴离子(第一种)和锂阳离子组成的接触离子对。将溶剂从乙醚交换为DME(1,2-二甲氧基乙烷),得到溶剂分离的离子对。这两种配合物均表现出顺磁性,因此必须通过X射线衍射进行结构研究。使用DFT计算可以更好地理解这些配合物的电子结构。
