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 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.
