The gas-phase Ag+(CH3OH)n ions are studied by infrared photodissociation spectroscopy in the OH-stretch region. An analysis of the spectra with the aid of density functional theory calculations suggests that a coordination number of three is favored in the cases of Ag +(CH3OH)2·N2, Ag +(CH3OH)3, Ag+(CH 3OH)5, and probably of Ag+(CH 3OH)4. For the first two complexes, two-coordinated structures are also identified as minor isomers, which are indicative of the 5s-4d hybridization in Ag+. The coordination geometries of Ag +(CH3OH)n are similar to those of Ag +(H2O)n, but different from tetrahedral coordinations of Ag(I) commonly found in neat solvents.
