Au(I) complexes of the type RCOOAuL, where R=C6F13, C7F15, C8F17, C9F19, C6F5, OOC(C3F6) and L - trimethylphosphine (Me3P) were synthesized and characterized by spectroscopic (IR, (13)C, (19)F, (31)P NMR) and thermal methods. Spectroscopic results favour two coordinated Au(I) with unidentate bonded trimethylphosphine and carboxylates, whereas in the case of hexafluoroglutarate a dimeric structure has been found. The mode of carboxylates binding was proposed basing on the chemical shift of COO group in (13)C NMR spectra and splitting of COO asymmetric and symmetric vibrations bands. Thermal decomposition proceeds in a multistage way that results in metallic gold. Decomposition temperatures and thermal stability of the studied complexes depend on the length of the perfluorinated chain.
