one-dimensional chains in the solid state, even in the presence of excess Ag(I). Structurally diverse coordination polymers exhibiting different coordination numbers and geometry were characterized by single crystal X-ray crystallography. Our results demonstrate that a modification to the ligand, distal from the binding site, affects the coordination chemistry and supramolecular structure of these complexes.
首次制备了易于官能化的联嘧啶化合物,并探索了它们与银盐的配位化学。解决方案11 H NMR光谱实验表明,配体与银(I)盐快速形成络合物,并且在第一位点的配位抑制了第二阳离子与配体的配位,因此有利于溶液中的1:1配位。即使存在过量的Ag(I),这些1:1单元也可以固态自组装成一维链。通过单晶X射线晶体学表征表现出不同配位数和几何形状的结构多样的配位聚合物。我们的结果表明,在结合位点远端对配体的修饰会影响这些配合物的配位化学和超分子结构。
