Fluxional platinum and “naked” alkynyl rods : The first example of a Pt 3 C 2 complex with a “naked” C≡C 2− unit linked to three unsupported platinum(II) fragments has been reported and characterized by X‐ray crystallography. An interesting fluxional motion, which involves σ–π alkynyl exchange, has been revealed in solution (see figure). The photophysical properties have been studied and correlate with theoretical calculations.
