摘要

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 P3(1)21 with lattice parameters a 12.5919(1) and c = 15.4978(1) Angstrom. Due to fourfold twinning a large cubic unit cell with a 26 A 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 If net. In the cavities of the framework the Ag+ ions are incorporated. [References: 21]
