Abstract
Ag(I) complexes in ethanol and 2-methyltetrahydrofuran solid solutions were reduced by gamma-irradiation at 77 K. The hyperfine coupling constants due to silver observed in the ESR spectra of the reduction products indicate t hat the excess electron is localized mainly on the 5s orbital of the silver atoms for Ag(I)beta-diketones but not for Ag(I) complexes coordinated with nitrogen atoms in either solid. It has been found that the isotropic hyper fine coupling constants of Ag-0 in Ag(O)-beta-diketones depend on the solve nt. (C) 1999 Elsevier Science B.V. All rights reserved.
