【摘要】 合成了15种新的镧系高氯酸盐和二缩三乙二醇二甲醚的配合物,证明其组成为 Ln（ClO₄）·EO₃Me₂·5H₂O（Ln=La—Lu,Y）.由于端基的改变明显影响配位能力,因而引起配合物组成及物化性质等一系列变化.本文尝试以^C NMR 弛豫速率法获取直链聚醚配合物中的结构信息,并探讨其构象问题,实验证明成配后配体采取全 TGT 构象.更多还原

【Abstract】 Fifteen new complexes of lanthanide perchlorates including yttrium withtriethylene glycol dimethyl ether have been synthesized and characterized.Thecomposition of them is Ln（ClO₄）₃EO₃Me₂·5H₂O （Ln=La—Lu,Y）.Terminal groupsof ligand play an important role in the complexation and cause a great change intheir properties.¹³C NMR relaxation rate of complexes has been investigated forgetting the structure information.It has been shown that the ligand in the complexeshas TGT conformation.更多还原
