The cluster [Au2Ag2(C2Ph)4(PPh3)2)] has been prepared by the reaction of Ph3PAuC2Ph with [AgC2Ph]n, and by that of Ph3P with the polymer [AuAg(C2Ph)2]n. The structure of the new cluster involves a linear arrangement of two phenylacetylide groups about each gold atom, with each silver atom asymmetrically π-bonded to two triple bonds and one phosphine ligand.
