What sort of structures do cuprates have? Hitherto, this question could chiefly be answered X‐ray crystallographically only in the case of “exotic examples.” However, it has now been possible to elucidate the structure of 1 , an astonishingly stable, unsubstituted phenylcuprate. It can be described as an eight‐membered ring of almost linear CuPh 2 moieties and trigonal‐planar coordinated Li atoms.
