摘要
通过二价过渡金属元素(Cu、Ni和Co)与邻香草醛缩2,6-二氨基吡啶(H2L)在甲醇溶液中的反应,成功地制备了三种二价过渡金属的配合物.通过元素分析和热重分析对配合物进行了表征,确定配合物的组成为CuL.5H2O、NiL.5H2O、CoL.2H2O.通过对配合物的红外光谱和紫外光谱测定与归属,推测在三个过渡金属Schiff碱配合物中配体是通过酚羟基的氧原子和亚氨基的氮原子进行配位的.通过循环伏安法对配合物的电化学行为进行了研究.
Three coordination compounds of transition elements（Cu, Ni and Co） with N,N＇-bis（o- vanillyidene）-2,6-pyridinediamine （H2L） were prepared in presence of methanol. The complexes have been characterized by elemental analysis and thermogravimetris analysis. Compositions of these complexes were confirmed to be CuL ·5H2O, NiL · 5H2O and CoL · 2H2O. IR spectra and UV spectra of the complexes are described. The results show that two phenolic oxygen and two imino nitrogen atoms in H2L coordinate to M（II） ions. The cyclic voltametric behaviors of the complexes were also reported.
