Schiff碱Ni(Ⅱ)单核及Ni(Ⅱ)-Fe(Ⅲ)异双核配合物的合成表征及电化学性质

Synthesis, Charactrization and Electrochemical Properties of Ni(Ⅱ) Mononuclear and Ni(Ⅱ)-Fe(Ⅲ)Heterobinuclear Schiff Base Complexes

合成了二(3 羧基水杨醛叉)缩1,3 丙二胺(TS)Schiff碱配体的Ni(Ⅱ)单核配合物Na2Ni(TS)·2H2O和Ni(Ⅱ) Fe(Ⅲ)异双核配合物NiFe(TS)Cl·2.5H2O 用元素分析、摩尔电导、IR光谱、UV光谱及差热分析对配合物的组成和结构进行了表征 采用循环伏安法研究了配合物的电化学性质。

Mononuclear complex Na_(2)Ni(TS)·2H_(2)O and heterobinuclear complex NiFe(TS)Cl·(2.5H_(2)O), where TS is the Schiff base N,N′-bis(3-carboxylsalicylidene)trimethylenediamine, were synthesized and characterized by elemental analysis, molar conductivity, thermal analysis, IR and UV-visible spectra. The electrochemical properties of the complexes were examined by cyclic voltammetry in DMSO; The results show that the coordination of the second metal ion Fe^(3+) has the electrochemical stability of the nickel(Ⅱ) ion increased.
