To force metal ions in heterometallic coinage metal complexes into preset compartments, we have synthesized a ligand with two N-heterocyclic carbenes (NHCs) separated by a methylene bridge and two bipyridine moieties tethered to each NHC moiety. By using this ligand, tetranuclear heterodimetallic gold/copper and gold/silver complexes were obtained. These complexes show an unprecedented V-shape or linear MAuM (M = Cu, Ag) configuration in the solid state. The photophysical properties of the new compounds are significantly affected by the complexed metal ions.
为了将异金属铸币金属配合物中的金属离子强制引入预设的隔室中，我们合成了一种配体，该配体具有两个由亚甲基桥隔开的N-杂环卡宾（NHC）以及连接到每个NHC部分的两个联吡啶部分。通过使用这种配体，获得了四核异二金属金/铜和金/银配合物。这些配合物在固态下呈现出前所未有的V形或线性MAuM（M = Cu，Ag）构型。新化合物的光物理性质受到配位金属离子的显著影响。
