Abstract
우라닐 이온, UO2+와 Schiff-base 와의 착화합물이 글리실글라이신과 살리실알데히드, 2-히드록시-1-나프트알데히드, 2,3-디히드록시 벤즈알데히드 그리고 2,4-디히드록시 벤즈알데히드와의 축합에 의해 합성되었으며 이들 착화합물의 특성을 원소분석, 전도도 측정, 자기화율 측정, UV, IR, NMR 스펙트라와 DTA, TG, DSC 결과를 이용하여 조사하였다. 구조와 열분해 메카니즘이 제안되었다.

Complexes of uranyl ion UO2+2with Schiff-bases obtained by condensing glycylglycine with salicylaldehyde; 2-hydroxy-1-naphthaldehyde, 2,3-dihydroxybenzaldehyde, and 2,4-dihydroxybenzaldehyde have been synthesized and characterized through elemental analysis, conductivity measurements, magnetic susceptibility determinations, u.v., i.r. and 1H nmr spectra as well as d.t.a., t.g. and d.s.c. techniques. Structures and mechanisms of thermal decomposition are proposed.
