A spectroscopic and theoretical investigation of charge transfer complexes between silver and nitric oxide:: Infrared spectra and density functional calculations of AgNO+,0,- and Agx(NO)y clusters (x, y=1, 2) in solid argon and neon

Laser-ablated silver atoms are reacted with nitric oxide, and products are isolated in solid argon and neon. The pseudo-hyponitrite complex Ag(NO)(2)Ag is the dominant product, with AgNOAg and AgONNO present in smaller yields. These complexes are shown using density functional theory to include significant charge transfer from silver but are not as ionic as the analogous alkali metal complexes of nitric oxide. The neutral and ionic mononitrosyls AgNO+, AgNO, and AgNO- are also observed, and qualitative trends in bond lengths and frequencies in this series are discussed.
