A flexible building block : Flexible tetragold(I) chain complexes supported by a new single methylene‐bridged tetraphosphine ligand were synthesized and further transformed into discrete linear octagold(I) {Au 8 } and cyclic hexagold(I) {Au 6 } structures by reaction with KI and NaAuCl 4 , respectively (see picture, Au purple, Cl dark green, PF 6 light green, I pink). The tetragold complexes are also luminescent at room temperature.
