geometry for mononuclear macrocyclic zinc complex. The 1H NMR spectrum and X-ray crystal structure of the macrocyclic Zn(II)–Ni(II) complex demonstrated a C1 symmetric geometry with a five-membered heterocycle ring attached to the diethylenetriamine link as a result of an intramolecular rearrangement. The explanation for these topological transformation and intramolecular rearrangement as well as electrochemical
摘要 通过逐步方法制备了一种新型大双环杂双核 Zn(II)-Ni(II) 配合物,其具有苯酚基二室配体,具有连续的六 (N4O2) 和五齿 (N3O2) 配位位点。制备的单金属和双金属大环配合物通过元素分析、红外光谱、核磁共振光谱和摩尔电导测量进行表征。表征结果证实了单核大环锌配合物的预期 C2 对称几何形状。大环 Zn(II)-Ni(II) 配合物的 1H NMR 光谱和 X 射线晶体结构证明了 C1 对称几何结构,由于分子内重排,五元杂环连接到二亚乙基三胺键上。
