The formula of the title compound is no printing error! Instead it announces unusual chemistry. This oxide is subvalent with respect to silver and contains an extremely electron‐poor Ag 6 4+cluster. It therefore seems almost paradoxical that the yellowish shiny metallic oxide is formed under elevated oxygen pressure, that is, under oxidizing conditions. In the structure (shown alongside) the relative arrangement of Ag 6 octahedrons and GeO 4 tetrahedrons are illustrated.
