    Description / Table of Contents: The Structure of the Fluoride Hydrates CoAlF5 · 7H2O and MnFeF5 · 7H2OSingle crystals of fluoride hydrates CoAlF5 · 7H2O and MnFeF5 · 7H2O have been prepared and characterized by X-ray methods. The Co/Al compound crystallizes in space group C2/m (a = 1091.7(7), b = 1386.3(14), c = 652.5(6) pm, β = 100.30(6)°, Z = 4). H2O/F- disorder occurs over two trans positions in the ligand sphere of Al3+, whereas the Mn/Fe compound shows an ordered variety with [FeF6]3- and [FeF4(H2O)2]- anions crystallizing in space group C2/c (a = 1118.2(3), b = 1416.8(4), c = 1326.4(3) pm, β = 100.51(2)°, Z = 8). Both structures exhibit strong hydrogen bonds between [MII(H2O)6]2+ cations and the fluorine ligands in the coordination sphere around the tervalent metals. The complex cations and anions are grouped like in CsCl type salts.
    Notes: Erstmals wurden die Fluoridhydrate CoAlF5 · 7H2O und MnFeF5 · 7H2O in einkristalliner Form präpariert und röntgenographisch untersucht. Die Co/Al-Verbindung kristallisiert in der Raumgruppe C2/m (a = 1091,7(7), b = 1386,3(14), c = 652,5(6) pm, β = 100,30(6)°, Z = 4) mit H2O/F--Fehlordnung auf 2 trans-ständigen Lagen in der Al3+-Koordinationssphäre, wogegen die Mn/Fe-Verbindung eine geordnete Variante mit den Anionen [FeF6]3- und [FeF4(H2O)2]- in Raumgruppe C2/c bildet (a = 1118,2(3), b = 1416,8(4), c = 1326,4(3) pm, β = 100,51(2)°, Z = 8). Beiden Strukturen gemeinsam sind starke Wasserstoffbrückenbindungen zwischen den [MII(H2O)6]2+-Kationen einerseits und der Fluoridkoordinationssphäre der dreiwertigen Metalle andererseits. Die komplexen Kationen und Anionen sind wie im CsCl-Typ angeordnet.
