Varying the Frameworks of Novel Silver(I) Coordination Polymers with Thioethers by Altering the Backbone or Terminal Groups of Ligands

A series of novel silver−thioether metal−organic supramolecular architectures forming different
frameworks are constructed by the direct reactions of AgI perchlorate with a series of di- or trithioether ligands
which are closely related in structure. In the crystal structures of the four complexes, a variety of coordination
modes of the AgI centers due to the conformation freedom or steric hindrance have been observed, indicating that
the nature of the ligands is a determining factor in controlling the structural topology of the metal−organic
supramolecular architectures.

本研究通过高氯酸银(I)与一系列结构相近的二硫醚或三硫醚配体的直接反应，构筑得到一系列具有不同框架结构的新型银-硫醚金属有机超分子架构。在四种配合物的晶体结构中，因配体的构象自由度与空间位阻效应，银(I)中心展现出多种配位模式，这表明配体的固有性质是调控金属有机超分子架构结构拓扑的决定性因素。
