    Description / Table of Contents: On Formation and Structure of Mg(HSO4)2 · H2OMg(HSO4)2 reacts with water under formation of its monohydrate, Mg(HSO4)2 · H2O. This reaction proceeds crystallographically oriented and is reversible. Mg(HSO4)2 · H2O crystallized monoclinic in the space group P21/n, with the unit cell parameters a = 8.623(2), b = 5.014(1), c = 15.428(3) Å, β = 101.32(2)°, V = 654 Å3, Z = 4. The crystal structure of Mg(HSO4)2 · H2O consists of two types of SO3OH-tetrahedra connected over three common oxygen atoms with three different MgO6-octahedra. This motif forms layers parallel to the xy-plane. The layers are arranged at a distance of c/2 and are linked via hydrogen bonds which start from the water of crystallization situated between the layers.
    Notes: Mg(HSO4)2 bildet durch Wasseraufnahme das Monohydrat Mg(HSO4)2 · H2O. Diese Reaktion verläft kristallographisch orientiert und ist reversibel. Mg(HSO4)2 · H2O kristallisiert in der monoklinen Raumgruppe P21/n mit den Gitterkonstanten a = 8,623(2), b = 5,014(1), c = 15,428(3) Å, β = 101,33(2)°, V = 654 Å3, Z = 4. Die Kristallstruktur des Mg(HSO4)2 · H2O ist charakterisiert durch 2 Sorten von SO3OH-Tetraedern, die jeweils über drei gemeinsame Sauerstoffatome mit drei verschiedenen MgO6-Oktaedern verknüpft sind. Dieses Strukturmotiv bildet Schichten parallel zur xy-Ebene. Die Schichten folgen im Abstand von c/2 aufeinander und werden über H-Brücken miteinander verknüpft, die vom Hydratwasser ausgehen, das zwischen den Schichten positioniert ist.
