Linking polymetallic cages can be a method for creating new structures and new properties. In this tutorial review we use heterometallic anti-ferromagnetically coupled rings (AF-rings) as exemplars for three approaches that can be used to link cage compounds. The first of three routes involves an ion-pair interaction supported by hydrogen-bonding interactions, which allows the synthesis of hybrid rotaxanes among other materials. The second route involves functionalising the exterior of the AF-ring so that it will act as a Lewis base; complexes involving coordination of pyridine to bridging monometallic and dimetallic fragments are discussed. The third route involves creating a vacancy on one site of the AF-ring, and then using the ring as a Lewis acid. Di-imine ligands can then be used to link the AF-rings into dimers. A brief discussion of the physical properties of these systems is also included.
链接多金属笼合物可以是创造新结构和新性能的一种方法。在本教程综述中，我们使用反铁磁耦合的杂金属环（AF-环）作为范例，介绍了三种可以用来连接笼状化合物的方法。三种方法中的第一种涉及由氢键支撑的离子对相互作用，这允许在其他材料之间合成混合轮烷。第二种方法涉及功能化 AF-环的外部，使其充当路易斯碱；讨论了涉及吡啶桥联单金属和双金属片段配位的配合物。第三种方法涉及在 AF-环的一个位置上制造空位，然后将环用作路易斯酸。然后可以使用二亚胺配体将 AF-环链接成二聚体。还简要讨论了这些系统的物理性质。
