Abstract

[{C7F15CO2}2AgAu(PPh3)]2 is obtained in good yield from the reaction of [C7F15CO2Ag] with [ClAuPPh3] in THF solution. The crystal structure shows a zig-zag Au–Ag–Ag–Au core with fluorocarboxylate ligands bridging the Au–Ag and Ag–Ag bonds and triphenylphosphine groups bound to Au. Electrodeposition from acetonitrile yields Au–Ag alloys. The deposited alloys are Ag rich and the composition varies with deposition potential.
