Multinuclear NMR Characterization of Ag(I) Perfluorinated Carboxylates Complexes with Bis(diphenylphosphino)methane

Ag(I) perfluorinated carboxylate complexes with bis(diphenylphosphino0methane (dppm) of general formula [Ag2(RCOO)2(dppm)], where R=CF3, C3F7, C4F9, C6F13, C9F19 were synthetized and spectroscopically (1H,13C,31P,19F, NMR and IR) characterized. Temperature variable 31P NMR spectra were recorded and 1J(107Ag-31P), ysis of coordination shifts and coupling constants are in favour of dimetric trigonal Ag(I) complexes with bridging carboxylates and dppm in solution. IR spectra suggest the same coordination mode in the solid state.
