Preparation and nuclear magnetic resonance spectroscopy of [Ag2{µ-CH2(PPh2)2}3][O3SCF3]2, a disilver(I) complex with three bridging CH2(PPh2)2 ligands

Abstract

[Ag2(µ-dppm)3][O3SCF3]2[dppm = bis(diphenylphosphino)methane] has been prepared and characterized by 31P n.m.r. spectroscopy. Variable-temperature n.m.r. studies revealed that the Ag–P bonds are kinetically stable on the n.m.r. time-scale below 233 K. At ambient temperature there is intermolecular ligand exchange whereas at intermediate temperatures intramolecular inter-metal exchange of the phosphorus atoms of the dppm ligands occurs.
