including the parent compound, N,N‘-dialkyl variants, and the first N,N‘-di-pendant-arm derivatives have been synthesized by a short, efficient, and conceptually novel approach. Their copper(II) complexes have been prepared, and four of these were structurally characterized by X-ray diffraction. In all four complexes, the cross-bridged tetraamine ligand was found to be cis-folded, coordinating the metal
已经合成了一系列 1,4,8,11-四氮杂双环 [6.6.2] 十六烷配体,包括母体化合物、N,N'-二烷基变体和第一个 N,N'-双侧悬臂衍生物通过一种简短、高效且概念新颖的方法。已经制备了它们的铜 (II) 配合物,其中四种通过 X 射线衍射进行了结构表征。在所有四种配合物中,发现交叉桥接的四胺配体是顺式折叠的,使用所有四个氮孤对在其分子裂缝内配位金属阳离子。对于三个配合物,发现了理想化的四角锥体和三角双锥体配位之间的几何结构,而在双悬臂交叉桥接仙客来的配合物中发现了扭曲的八面体铜配位。
