An Ag(I) metallacycle obtained unexpectedly during the preparation of Pd(II) complexes of the bifunctional ligand 5-([2,2'-bipyridin]-5-yl)pyrimidine-2-amine () has been characterized using X-ray structure determination as a binuclear, metallacyclic species Ag, where both the bipyridine and pyrimidine-N donors of are involved in coordination to the metal. The full coordination environment of the Ag(I) defines a case of highly irregular 4-coordination. In the crystal, the Ag-metallacycles assemble into one-dimensional supramolecular metalladynamers linked together by hydrogen-bonding interactions.
在制备双功能配体 5-([2,2'-联吡啶]-5-基)嘧啶-2-胺 () 的 Pd(II) 配合物的过程中，意外得到了一个 Ag(I) 金属环，通过 X 射线结构测定对其进行了表征，结果表明该金属环为双核、金属环物种 Ag，其中双吡啶和嘧啶-N 供体都参与了金属的配位。Ag(I) 的完全配位环境定义了一个高度不规则的 4 配位情况。在晶体中，Ag 金属环通过氢键相互作用组装成一维超分子金属动态聚合物。
