Darstellung und Kristallstruktur von Ag2MnO4

Synthese and Crystal Structure of Ag₂MnO₄ Single crystals of Ag₂MnO₄ have been grown from aqueous solution. The crystal structure has been solved and refined using diffractometer data (Pnma, a = 999.8(2); b = 698.9(1); c = 547.4(2) pm). The mean bond-length Mn? O within the tetrahedral anions is 167.9 pm. In spite of similar lattice constants and identical space group, Ag₂MnO₄ is not isostructural to Olivine. The structural differences are discussed.
