A promising new ion‐conducting material , the title compound, can be prepared from AgMnO 4 and Ag 2 O (1:1) at 970 °C under 5 kbar O 2 . The Mn 8 O 16 framework forms channel‐like cavities of face‐sharing cubes. The Ag ⊕ ions occupy the bottle‐necks of this one‐dimensional diffusion channel as regular lattice sites. This constitutes the first example of square‐planar coordinated Ag ⊕ ‐ions.
