dc.description.abstract [EN] Cationic mono-, di-, tri-and tetra-nuclear silver complexes with Buchwald-type phosphane (XPhos) and cyclooctatetraene (COT) have been synthesized and characterized. Formation of [(XPhos-Ag) n(COT)][SbF6](n) (n = 1 and 2) complexes was confirmed by single-crystal X-ray crystallography and multinuclear NMR spectroscopy. Variable-temperature NMR spectroscopy in CD2Cl2 solution shows the fluxionality of the COT ring in the mono-Ag(I) XPhos complex. Fluxionality of COT was also confirmed in the case of the di-Ag(I) XPhos complex by solid-state and solution P-31 NMR spectroscopy. The C-C bond cleavage of coordinated acetonitrile [XPhos-Ag(I)-NCCH3] resulting in cyanide bridged Ag cluster formation [(XPhos-Ag)(2)(mu-CN)(n)(mu-Ag)(n-1)] (n = 1, 2, 3 and 4) upon light excitation of [(XPhos-Ag)(n)(COT)] was confirmed by HRESI-MS, UV-Absorption and HR-TEM. es_ES
