摘要：

A thrust in the right direction: Two different disk-shaped ligands (a tris-monodentate and a hexa-monodentate ligand) and three Ag+ ions have been used as bearings and balls, respectively, in the construction of a molecular thrust ball bearing (see schematic representation). Rotation occurs through a combination of intramolecular, reversible multipoint ligand exchange and flip motions that act in concert.
