show that, in the former complex, the thioether sulphur remains uncoordinated giving rise to an eight-membered chelate ring. In the latter complex each pentadentate ligand binds to both metal ions forming an amide complex with one and an amine complex with the other. The two rhenium atoms are components of a 10-membered dimetallocyclic ReSCH2CH 2N}2 ring.
摘要[ReOCl4]-与席夫碱配体HOC6H42-CHN(CH2)2} 2S在乙醇中的反应,得到单体络合物[ReO(OEt)OC6H42-CHN(CH2)] 2} 2S]。但是,通过还原席夫碱获得的使用胺配体HOC6H42-CH2NH(CH2)2} 2S的类似反应可得到双核络合物[ReO 2-(OC6H42-CH2N(CH2)2S(CH2) 2NHCH2)C6H4O} 2ReO]。这些配合物的分子结构已经确定,表明在前一种配合物中,硫醚硫保持不配位,从而形成八元螯合环。在后者的络合物中,每个五齿配体与两个金属离子结合,形成一个酰胺络合物和一个胺络合物。这两个rh原子是10元双金属环ReSCH2CH2N} 2环的组成部分。
