乙二胺水杨醛Schiff碱镍配合物的合成

Synthesis of the Complex of Nickle () with EthylenediamineSalicylaldehyde Schiff Base

合成了乙二胺水杨醛Ｓｃｈｉｆ碱及其与四种不同镍盐（Ｘ＝ＮＯ－３、ＳＯ２－４、Ｃｌ－、Ａｃ－）的配合物。采用元素分析、红外光谱、紫外－可见光谱和电导测定等实验手段对配合物的组成结构进行分析鉴定。实验结果表明，当阴离子配位能力弱时，一般不参与配位，相对较强时，可与中心离子配位，四种不同阴离子的盐分别得到两种结构不同的配合物。

Ethylenediamine salicylaldehyde Schiff base and its complexes with Nickel were synthesized. The composition and structure of the complex were characterized by elementary analysis, IR, UVVis and electrical conductivity. The experimental results show that the weakligand anions, such as NO-3, Cl- and SO2-4, do not usually coordinate with centerion Ni2+, and the stronger coordination Ac- anion is coordinated with centerion Ni2+. Two kinds of different structure complexes were obtained from Ni(NO3)36H2O,NiSO4,NiCl2 and Ni(Ac)2, and their possible structure formulas were suggested.
