5,8,11,14,17-hexaazaoctadecane, form stable complexes with CuI in aqueous solutions. On the other hand 2,5,8-trimethyl-2,5,8-triazanonane, does not. This indicates that the stabilization of CuI by tertiary amine ligands in aqueous solutions requires at least four nitrogens. The electronic spectra and the electrochemical properties of the [CuLi]2+ complexes over a wide pH range were studied and potentiometric
2,5,8,11-四甲基-2,5,8,11-四氮杂十二烷,2,5,8,11,14-五甲基-2,5,8,11,14-五氮杂十五烷和2,5,8 1,11,14,17-六甲基-2,5,8,11,14,17-六氮杂十八烷在水溶液中与Cu I形成稳定的配合物。另一方面,没有2,5,8-三甲基-2,5,8-三氮杂壬烷。这表明水溶液中叔胺配体对Cu I的稳定作用需要至少四个氮原子。电子光谱和的[CUL的电化学特性我] 2+复合物在宽的pH范围内进行了研究和电势滴定作了含有Cu的等摩尔浓度的溶液II和L我。讨论了这些解决方案中存在的配合物的性质。
