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R_1值以下列顺序递增:R_1(Mn)R_1(Zn).讨论了该系列络合物薄层色谱比移值(R_1)与紫外光谱R带λmax变化关系的一致性.
In this paper, glycine, Schiff bases of salicylaldehyde and their complexes of Mn (Ⅱ), Co (Ⅱ), Ni (Ⅱ) Cu (Ⅱ) and Zn (Ⅱ) were synthesized. Elemental analysis and molar conductance The results showed that the coordination complex of aminosalicylaldehyde Schiff base was 1: 1 and the complex was non-electrolyte. The complex was eluted with methanol-ethanol-acetone-water [2.22: 4.44 : 3.33: 0.5 (volume ratio)] as the mobile phase, the complexes of each component were satisfactorily separated and the R_1 values increased in the following order: R_1 (Mn) R_1 (Zn). The consistency of the relationship between the thin film chromatography ratio shift (R_1) and the λ band of the ultraviolet spectrum was discussed.
