In gear : Dynamic 1 H NMR studies on some organometallic platinum(II) compounds reveal a synchronism between rotation around the PtP bond and the oscillation of a phenanthroline ligand between two nonequivalent exchanging sites. The system behaves as a molecular‐sized analogue of a mechanical gear (see picture; C gray, N blue, O red, P purple) whose dynamic properties can be tuned through small structural changes.
