奎宁与Cu(I)Cl和Cu(I)Br反应,分别得到Cu 5Cl 9(H2 Quinine)2(1)和Cu 3Br 7(H2 Quinine)2(H2O)(2),它们具有一维聚合物结构。1中的阴离子链包含Cu 4Cl 62-金刚烷型聚集体,其通过CuCl 32-桥连接到两个相同的单元,2中的Cu(I)中心具有由桥连和末端溴离子形成的扭曲四面体环境。1是第一个表现出铁电行为的同手性金属有机配位聚合物。
The reactions of quinine with Cu(I)Cl and Cu(I)Br afford Cu5Cl9(H2Quinine)2 (1) and Cu3Br7(H2Quinine)2(H2O) (2), respectively, with 1D polymeric structures. The anionic chain in 1 contains Cu4Cl62- adamantane-type aggregates that are linked to two identical units by CuCl32- bridges, and the Cu(I) centers in 2 have a distorted tetrahedral environment formed by bridging and terminal bromide ions. 1 is the first homochiral metal-organic coordination polymer exhibiting ferroelectric behavior.
