【摘要】 本文合成了甘氨酸、苯氨酸水杨醛席夫（Schiff）碱及其Mn（Ⅱ）、Co（Ⅱ）、Ni（Ⅱ）Cu（Ⅱ）和Zn（Ⅱ）的络合物.元素分析和摩尔电导测定的结果证明,氨基水杨醛Schiff碱的3d金属络合物配位比为1:1,络合物为非电解质.在硅胶G板上,以甲醇-乙醇-丙酮-水[2.22:4.44:3.33:0.5（体积比）]为流动相研究了络合物的薄层色谱行为,各组分络合物得到了满意的分离,且R₁值以下列顺序递增:R₁（Mn）<R₁（Co）<R₁<（Ni）<R₁（Cu）>R₁（Zn）.讨论了该系列络合物薄层色谱比移值（R₁）与紫外光谱R带λmax变化关系的一致性.更多还原

【Abstract】 The some transition metal complexes of Schiff base derived from salicylaldehyde with glycine and phenylalanine were synthesized. The purity of the products obtained was confirmed by elemental analysis. The thin-layer chromatography behavior of complexes was studied on silica gel G plate with methanol-ethanol-acetone-water[2. 22 : 4. 44 : 3. 33 : 0. 5 (V/V)] as mobile phase. The results show the Rf values of complexes to increase as follow: Rf(Mn)<Rf(Co)<Rf(Ni)<Rf(Cu)>Rf(Zn) , and R band λmax values of ultraviolet spectrum change in the same direction as the Rf values.更多还原
