Abstract

Partially ¹³C-labeled alkali dicyanoaurates M[Au(CN)₂] were prepared and investigated by NMR and IR spectroscopy in aqueous solution. For the range of concentration investigated the data obtained under standard conditions provided no evidence for anion association. The salt [Ph₃PNPPh₃] [Au(CN)₂] was also prepared and the crystal structure of the dichloromethane solvate determined. There is no anion aggregation in the crystal, and short contacts of the anions are only discernible with the solvent molecules. A literature survey of crystal structure data for dicyanoaurate(I) salts (almost 35 entries) show that inter-anionic contacts are only observed in structures with small cations or with cations exerting a directional influence.
