Innocent behavior of a typical non‐innocent ligand has been observed for the first structurally characterized discrete metal complex with tetranucleating TCNQ. The coordination of four [Re(CO) 3 (bpy)] + units (see picture: C: black, N: green, O: blue, Re: red) facilitates the reduction of the already excellent π‐acceptor molecule TCNQ by a further 0.74 V! TCNQ=7,7,8,8‐tetracyano‐ p ‐quinodimethane, bpy=2,2′‐bipyridine.
