    Description / Table of Contents: Darstellung und Kristallstruktur von Kaliummangancyclodecaphosphat-octadecahydrat: K2Mn4P10O30 · 18 H2ODie Titelverbindung, ein neues Cyclodecaphosphat, wurde durch Fällung aus wäßriger K10P10O30-Lösung hergestellt. Das in Wasser wenig lösliche Salz kristalliert monoklin in der Raumgruppe P21/a mit den Gitterkonstanten a = 14,546(10), b = 15,211(10), c = 9,860(6) Å, β = 105,12(4)°.Die Kristallstruktur wurde unter Verwendung von 6501 unabhängigen Reflexen gelöst, der R-Wert beträgt 0,044.Die zentrosymmetrischen Ringanionen sind relativ weit voneinander entfernt und in einer pseudotetragonalen Weise angeordnet, so daß parallel zur c-Achse große, die Wassermoleküle enthaltende Kanäle gebildet werden.
    Notes: The title compound, a new cyclodecaphosphate, was prepared by precipitation from an aqueous solution of K10P10O30. The sparingly soluble salt crystallizes monoclinic in the space group P21/a, with Z = 2, and the unit-cell dimensions a = 14.546(10), b = 15.211(10), c = 9.860(6) Å, β = 105.12(4)°.The crystal structure was solved using 6501 unique reflections with a final R-value of 0.044.The centrosymmetrical ring anions rather distant from each other and arranged in a pseudo-tetragonal way create, parallel to the c direction, large channels containing the water molecules.
