La(Ⅲ)、Nd(Ⅲ)、Tb(Ⅲ)、Er(Ⅲ)与二溴水杨醛缩乙二胺配合物的合成与表征及薄层色谱研究

Synthesis,Characterization and Thin layer Chromatography of Complexes of Lanthanide Nitrates with DbsalenH 2

合成了四种稀土双核配合物，其组成为Ｌｎ２Ｌ３（ＮＯ３）６·３Ｈ２Ｏ〔Ｌｎ＝Ｌａ（Ⅲ）、Ｎｄ（Ⅲ）、Ｔｂ（Ⅲ）、Ｅｒ（Ⅲ）；Ｌ＝３，５－二溴水杨醛缩乙二胺〕，并通过元素分析、红外光谱、紫外光谱、差热－热重及摩尔电导分析等手段，对合成的配合物进行了表征。

Four new complexes,namely Ln 2L 3(NO 3) 4 (NO 3) 2·3H 2O Ln=La(Ⅲ),Nd(Ⅲ),Tb(Ⅲ),Er(Ⅲ),L=DbsalenH 2=N,N′-ethylenebis(3,5-dibromosalicylideneimine) were synthesized by the reaction of lanthanide nitrates with DbsalenH 2.The complexes have been characterized by elemental,IR,UV,DTA-TG and molar conductance analyses.The thin layer chromatography behavior of the complexes was also studied.
