A series of single crystals of the complexes of nickel hydrate with chxn(chxn=1(R),2(R)-diaminocyclohexane)were synthesized in inert gas atmosphere and absolute methanol. The composition of the complexes were carried out by elemental analyses and IR. The cyclic voltammetry behavior of complexes of Ni(Ⅲ) and Ni(Ⅱ) with diaminocyclohexane and their influence were in-vestigated through the experiment. The experimental results showed that there was a partial reversible electrochemistry reaction of [NiⅡ(chxn)2]Br2and irreversible electrochemistry reaction on the platinum electrode for the complex of[NiI I(chxn)2Br]Br2,cy-clic voltammetry studies also showed that this complex could stabilize higher oxidation states of Ni(Ⅲ).%在惰性气体的保护下,以无水甲醇为溶剂合成了两种以chxn(chxn=1(R),2(R)-环己二胺)为配体的镍配合物[NiI I(chxn)2Br]Br2和[NiⅡ(chxn)2]Br2,元素分析和红外光谱对其进行表征确定其组成。通过循环伏安法对镍的二价和三价配合物的电化学行为进行了研究,讨论了电极反应过程及其配体对不同价态中心离子氧化还原电势的影响,结果表明在甲醇介质中镍的二价配合物在铂电极上的电化学反应是准可逆过程,三价配合物在铂电极上的电化学反应是不可逆过程,循环伏安测试表明此类配合物能稳定Ni(Ⅲ)。
