本文报道了3,5—二叔丁基—r—雷辛琐酸配体与稀土元素离子在水相中反应制得了13种固体配合物,它们均易溶于有机溶剂。元素分析结果和热重分析数据一致,并与预期的配合物组成吻合。红外光谱和核磁共振谱的测定数据表明RE(Ⅲ)与配体中的二个羧氧原子成键。紫外吸收光谱和差热—热重分析也对这类化合物的性质和结构进行了表征。
This paper reports 13 solid complexes of 3,5-di-tert-butyl-r-ras-octoate ligand and rare earth ions in water phase, all of which are soluble in organic solvents. The elemental analysis is consistent with the thermogravimetric data and is consistent with the expected composition of the complex. The data of IR and NMR spectra show that RE (Ⅲ) bonds with two carboxyl oxygen atoms in the ligand. UV absorption spectra and DTA-TGA also characterize the properties and structures of these compounds.
