Abstract
Metal complexes produced by depositing size selected Fe and Ag cluster cations in N2 and O2 matrices respectively are studied by infrared spectroscopy. Unknown species such as Fe(N2)x, Fe3 (N2)x and Ag3(O2)x are observed. The IR spectra of Ag+, Ag +2 and Ag +9 in excess O2 indicate that no complexes involving molecular oxygen are formed. However, the strong silver cluster UV-visible absorptions detected in Ar matrices disappear in the oxygen matrices, suggesting that silver-oxygen complexes are formed with dissociated oxygen.
