稀土与钛铁试剂,含氮杂环三元配合物的制备和性质

Syntheses and Properties of Rare Earth Elements with Tiron and Nitrogen Heterocyclic Ring

在水溶液中,制备了稀土(镧、钕、钆、铒)与钛铁试剂,含氮杂环(吡啶,喹啉,邻菲咯啉)三元固体配合物,通过化学分析及元素分析,确定了配合物的组成。测定了配合物的溶解性能,摩尔电导以及对红外,紫外,核磁共振和X射线粉末衍射等谱图的分析,推测了配合物的结构,并研究了3种类型配合物的共价程度。

The solid ternary complexes of rare earth elements(La,Nd,Gd,Er)with Tiron and nitrogen heterocylic ring have been synthesized in aqueous medium .Their chemical compositions are ascertained by chemical and elementary analyses , and their molar conductances, magnetic susceptibilities, IR, UV,~1H NMR spectra, thermal diagram,X-ray diffraction analysis and the solubilities in different solvents are also studied.
