The synthesis and crystal structures of ‘necklace’ 1-D coordination polymers with Cu2I2 nodes and ‘extended-reach’ heterocyclic bridging ligands
摘要:
Reaction of three 'extended-reach' bridging ligands with copper (I) iodide consistently produced 1-D coordination polymers with a necklace-type connectivity. These all consist of large macrocyclic rings sharing Cu2I2 nodes. In one case a potentially tripodal ligand acts in a hypodentate mode, with a pendent non-coordinated arm inserted into the cavity of an adjacent macrocycle. (C) 2014 Elsevier B. V.

A series of 1-D coordination polymers with varying Cu(II) bridging nodes were obtained by reactions of various copper salts with ‘extended-reach’ heterocyclic bridging ligands. Five of these have a ‘necklace-type’ topology, but differ in the nature of the Cu(II) linkages, some of which represent rare coordination motifs. In addition, cobalt(II) bromide was employed to generate a ‘necklace-type’ polymer
一系列具有不同 Cu(II) 桥接节点的一维配位聚合物是通过各种铜盐与“延伸范围”杂环桥接配体的反应获得的。其中五个具有“项链型”拓扑,但 Cu(II) 连接的性质不同,其中一些代表罕见的协调图案。此外,使用溴化钴 (II) 生成类似于其中一种铜 (II) 聚合物的“项链型”聚合物。
