    Description / Table of Contents: Neue Fluoromanganat(III)-Hydrate: Mn3F8 · 12H2O and AgMnF4 · 4H2ODie Fluoridhydrate Mn3F8 · 12H2O und AgMnF4 · 4 H2O wurden in Form von Einkristallen hergestellt und durch Röntgenbeugungsmethoden charakterisiert. Mn3F8 · 12H2O kristallisiert in Raumgruppe P1 (a = 623.0(3), b = 896.7(4), c = 931.8(4) pm, α = 110.07(2)°, β = 103.18(2)°, γ = 107.54(2)°, Z = 1); AgMnF4 · 4 H2O kristallisiert in Raumgruppe P21/m (a = 700.9(2), b = 726.1(1), c = 749.4(3) pm, β = 107.17(3)°, Z = 2). Beide Strukturen enthalten Jahn-Teller-verzerrte [Mn(H2O)2F4]-Anionen und zeigen ein komplexes Wasserstoffbrücken-Netzwerk zwischen Anionen und Kationen, nämlich [Mn(H2O)6]2+ in der ersteren und einem polymeren [Ag(H2O)2]--Kation in der zweiten Verbindung.
    Notes: Single crystals of fluoride hydrates Mn3F8 · 12 H2O and AgMnF4 · 4 H2O have been prepared and characterized by X-ray methods. Mn3F8 · 12 H2O crystallizes in the space group P1 (a = 623.0(3), b = 896.7(4), c = 931.8(4) pm, α = 110.07(2)°, β = 103.18(2)°, γ = 107.54(2)°, Z = 1); AgMnF4 · 4 H2O crystallizes in the space group P21/m (a = 700.9(2), b = 726.1(1), c = 749.4(3) pm, β = 107.17(3)°, Z = 2). Both structures contain Jahn-Teller-distorted [Mn(H2O)2F4]- anions as well as crystal water molecules and exhibit a complex hydrogen bond network between anions and cations, i. e. [Mn(H2O)6]2+ for the first and a polymeric [Ag(H2O)2]- cation for the second compound.
