The Cover Feature shows the alkene Bicyclopropylidene (bcp) that became (as well as its derivatives) a versatile C 6 building blocks for organic synthesis. It can undergo co‐cyclizations under palladium, nickel, and cobalt catalysis. However, despite the fundamental interest in the mechanism of these reactions, so far only a small number of transition metal complexes with bcp as ligand have been isolated and structurally characterized. Herein, we report the molecular structures of the nickel and copper complexes – [Ni(bipy)(bcp)] [Cu(bipy)(bcp)]PF 6 (anion not shown) – with bcp and 2,2′‐bipyridine as a co‐ligand.
