Resumen

The synthesis of pentafluorophenyl mono-or poly-nuclear gold(I) and/or gold(III) complexes with the tridentate ligand (PPh2CH2)3CCH3 (tdppme) are described in different coordination modes not represented thus far. The reaction of the free phosphine with gold(I) or gold(III) derivatives in different molar ratios gives [{Au(C6F5)}3( μ3-η3-tdppme)], [{Au(C6F5)}2( μ-η2-tdppmeO)], [Au(C6F5)3(η1-tdppme)] or [Au(C6F5)2(η2-tdppme)]Cl. The mononuclear derivatives further react with gold(I) or gold(III) species giving rise to di-or tri-nuclear complexes which contain the triphosphine acting as a μ3-η3, μ-η2, μ-η3 or η2 ligand.
