A tetranuclear organogold ferrocene derivative

1. A dicationic organogold ferrocenyl complex containing four gold atoms, namely {[(Ph3PAu)2C5H4]2Fe}++(BF4−)2, was obtained by the action of triphenylphosphinegold tetrafluoroborate on 1,1′-bis(triphenylphosphinegold)ferrocene. 2. The reaction of 1,1′-ferrocenyl-bis(triphenylphosphinegold) with HBF4 leads to cleavage of one C-Au bond and the formation of a binuclear cationic complex, namely, [C5H5 FeC5H4,(AuPPh3)2]+BF4−.
