Abstract: The analysis of the electronic structure of the isolated silver copper oxide Ag2Cu2O4 is presented along with its precursor Ag2Cu2O4 and similar binary oxides, Ag2O, AgO, CuO, and NaCuO2. The results for AgCu2O4 reveal an electronic distribution in which silver and copper share a delocalized valence scheme with both metals in formal oxidation states larger than the usual Ag(super I) and Cu(super II).
