本文合成了两个新的异双核咪唑桥联配合物[(NH_3)_5CoimM(tren)](ClO_4)_4·2H_2O[M=Cu(Ⅱ),Zn(Ⅱ);im=咪唑基],用热重差热、反射光谱、ESR 等手段进行表征,证实咪唑桥的存在.用pH 法结合计算机拟合,定量地模拟了异双核配合物中咪唑桥的断裂过程,表明在水溶液中,金属-咪唑键首先从非钴(Ⅲ)端断裂.
In this paper, two new heterodimetallic imidazole bridged complexes [(NH_3) _5CoimM (tren)] (ClO_4) _4 · 2H_2O [M = Cu The results showed that the imidazole bridges were found to exist in the heterodinuclear complex by pH method and computer simulation. The results showed that in the aqueous solution, the metal-imidazole The bond first breaks from the non-cobalt (III) end.
