The wings of the butterfly structure are widely extended in 2 (see picture, R=Me 3 SiCH 2 ), a complex with a dibismuthene ligand, which coordinates as a “side‐on”‐bridging, four‐electron donor to two tungsten atoms. Complex 2 is formed from the reaction of [W(CO) 5 (thf)] with alkylbismuth five‐ and three‐membered rings of cyclobismuthanes 1 , which exist in equilibrium.
