Abstract

Abstract : The intermetalloid cluster [Au9 GaCl2 (PPh3 )8 ] 2+ is obtained by using GaCp as a reducing agent in gold chemistry for the first time, being a rare exception in the borane-dominated field of reductants used for gold chemistry. Abstract : The low valent gallium(i ) compound GaCp was primarily used in gold cluster chemistry to synthesize the superatomic cluster [(PPh3 )8 Au9 GaCl2 ] 2+, complementing the borane-dominated set of reducing agents in gold chemistry, opening a whole new field for further research. Using density functional theory calculations, the cluster can be described by the jellium model as an 8-electron superatom cluster.
