The reaction of [Au8L8](NO3)2(L = PPh3) with the phosphine scavenger [RhCl(C8H14)2]2 yields [Au8L7]-(NO3)2, X-ray analysis of which reveals the Au skeleton to be a fragment of the centred icosahedron; the cluster to be a fragment; the cluster is an intermediate in the reactions of [Au9L8]3+, and its 197 Au Mössbauer spectrum lacks, like that of [Au9L8]3+, a separate resonance for the central Au atom.
