series of discrete Cp* Rh-based structures were constructed by selecting four ether bipyridyl ligands and three half-sandwich rhodium (III) bimetallic construction units. This study demonstrates a strategy to convert a binuclear D-shaped to a [2]catenane by changing the length of bridged ligands. Selective synthesis of [2]catenane and molecular Borromean rings can be achieved under similar conditions
