Abstract: | Preparative exploration of the system Ag—Mn—O under an elevated oxygen pressure yielded so far unknown Ag4Mn3O8. Single crystal X‐ray investigations have revealed a trigonal crystal system, space group P3121 with lattice parameters a = 12.5919(1) and c = 15.4978(1)Å. Due to fourfold twinning a large cubic unit cell with a ≈ 26Å is simulated. The structure, which was refined as a fourfold twin, is composed of MnO6 octahedra which are connected via common edges to a complex framework. The topology of this framework is closely related to the archetype cubic {10, 3} net. In the cavities of the framework the Ag+ ions are incorporated. |
