The donor/acceptor template-directed synthesis of a bis[2]catenane incorporating 2,2'-bipyridine ligands within both [2]catenane subunits and the self-assembly of a poly(bis[2]catenane) (see Figure for a schematic representation) is reported here. This molecule is a rare example of a mechanically interlocked coordination polymer-a class of intriguing supramolecular polymers with potentially unusual properties.
