    Description / Table of Contents: Salts of Halogenophosphoric Acids. XIX. Preparation of Copper(II) Monofluorophosphate Solvates and the Crystal Structure of Aquamonofluorophosphatocopper(II)-1,4-Dioxane 2/1, 2[Cu(H2O)PO3F] · C4H8O2The mixed solvate Aquamonofluorophosphatocopper(II)-1,4-Dioxane 2/1 1 was obtained by the reaction of aqueous solutions of NH4HPO3F and acidified (NH4)2PO3F, respectively, using 1,4-dioxane as precipitating agent. 1 crystallizes in the monoclinic space group C2/m with a = 2130.9(2), b = 655.45(6), c = 447.30(4) pm, b̃ = 96.207(7)° and Z = 2.Copper(II) monofluorophosphate-methanol 1/1, CuPO3F · CH3OH 2 was obtained by the reaction of copper(II) salts with alkaline or ammoniummonofluorophosphates in methanol. 1 and 2 react in the presence of water vapor to copper(II) monofluoro phosphate dihydrate, CuPO3F · 2H2O 3, which reacts reversibly with dioxan or CH3OH under formation of 1 and 2, respectively.
    Notes: Bei der Reaktion von wäßrigen NH4HPO3F- bzw. sauren (NH4)2PO3F-Lösungen mit Kupfer(II)-Salzen entsteht bei Zugabe von 1,4-Dioxan als Fällungsmittel das gemischte Solvat Aquamonofluoro-phosphatokupfer(II)-1, 4-Dioxan 2/1, 2[Cu(H2O)PO3F] · C4H8O2 1 als kristalliner Niederschlag. 1 kristallisiert in der monoklinen Raumgruppe C2/m mit a = 2130,9(2), b = 655,45(6), c = 447,30(4) pm, b̃ = 96,207(7)° und Z = 2.Die Umsetzung von kupfer(II)-Salzen mit Alkali- oder Ammoniummonofluorophosphaten in Methanol führt zur Bildung von Kupfer(II)-monofluorophosphat-Methanol 1/1, CuPO3F · CH3OH 2.1 und 2 wandeln sich in Anwesenheit von Wasserdampf in Kupfer(II)-monofluorophosphat-Dihydrat CuPO3F · 2 H2O 3 um, das durch Schütteln mit Dioxan bzw. Erhitzen mit CH3OH wieder in 1 bzw. 2 überführbar ist.
