X-Ray crystal structure of (tetraphenylimidodiphosphinato)silver(I): an unexpected tetranuclear complex with two modes of coordination of silver

Abstract

Potassium tetraphenylimidodiphosphinate reacts with silver nitrate to give, upon recrystallization from ethanol, an unexpected tetranuclear complex [Ag{N(OPPh₂)₂}]₄·2EtOH, the structure of which is established by X-ray crystallography; preliminary results concerning its use as a catalyst for the aerobic co-oxidation of alkenes and aldehydes are described.
