Mechanically interlocked structures are a kind of supramolecular entities with unique properties. They have attracted much attention not only because of their fascinating aspect of topologies, but also due to their great potential applications in nanotechnology, biology, and material science, as well as important bases for the preparation of molecular machines. This article summarizes new progress in the preparation of rotaxanes, catenanes, and other mechanically interlocked structures assembled via coordination interactions, especially focuses on the examples using metal-mediated coordination interactions as building ways cooperating with host-guest chemistry. Because coordination bonds are easy bonding, dynamically reversible, and easily controllable, the usage of metal-mediated coordination for constructing mechanically interlocked structures can greatly improve the preparation efficiency, and benefit to realizing the reversible regulation of mechanically interlocked structures.
