Abstract:

A new macrocyclic dinuclear nickel(Ⅲ) complex, prepared by the condensation of 2,6-diformylpyridine N-oxide with 1,3-diaminopropane in the presence of Ni(Ⅱ)Cl2•6H2O and formulated as Ni2LC16•C2H5OH•10H2O, was characterized by elemental analyses, infrared spectrum, differential thermal analysis (DTA), thermogravimetry(TG) and investigated electrochemically. The results show that two nickel ions are situated at the same chemical environments in the compound and the electrode reaction can he thought as a double electron transfer process which is irreversible. The diffusion coefficient is 4.07 x 10-6cm2•s-1. The Ni complex exhibited good thermal stability, it decomposed with loss of its organic portion and the formation of Ni2O3 as a final product at 563 ℃.
