title: Hexa- and octagold chains from flexible tetragold molecular units supported by linear tetraphosphine ligands.
abstract: 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.
