Organic-Ligand-Supported Two-Dimensional Carbonyl-Bridged Copper(I) Polymers

Two carbonyl-bridged copper polymers, [Cu2(μ-CO)L2]n (L = isonicotinate and nicotinate), have been synthesized by solvothermal reaction and structurally characterized. Both compounds contain a dicopper unit with one carbonyl bridge and two carboxylate bridges and have a two-dimensional network structure with carbonyl-bridged dicopper units as nodes and isonicotinate or nicotinate as connectors.两种羰基桥联铜聚合物[Cu₂(μ-CO)L₂]ₙ（其中L为异烟酸根（isonicotinate）和烟酸根（nicotinate））通过溶剂热反应合成，并完成了结构表征。两种化合物均含有由一个桥联羰基与两个羧酸根桥联构成的双核铜结构单元；二者均以羰基桥联双核铜单元作为节点、异烟酸根或烟酸根作为连接体，构筑得到二维网状结构。
