Mixed-metal-gold phosphine cluster compounds
WebThe field of metal cluster compounds has been studied with increasing interest in the past few years. Recent developments in the chemistry of molecular cluster compounds of gold are reviewed and the common structural types discussed. A comparison of the properties of these compounds with those of crystallites of gold and the bulk metal has been made.
