    Notes: Ammonium cyclooctaphosphate trihydrate, (NH4)8P8O24 · 3H2O, is monoclinic, Cc, with Z = 4 and the following unit-cell dimensions: a = 24.268(14), b = 6.700(3), c = 20.586(13) Å, β = 112,06(6)° Chemical preparation and crystal structure are reported. Using 4 668 unique reflections the atomic arrangement was determined with a final R value of 0.037. The organization of ring-anions and ammonium groups is almost centrosymmetrical but the location of the water molecules is not. The ring anion itself has a strong pseudo centrosymmetric conformation.

    Description / Table of Contents: Darstellung und Kristallstruktur von Guanidiniumcyclododecaphosphat-hexahydrat: [C(NH2)3]12P12O36 · 6H2ODie Titelverbindung, hergestellt durch Ionenaustausch aus dem Kaliumsalz, K12P12O36 · 9,5H2O besitzt einen zweiten neuen Strukturtyp von [P12O36]12- Ringanionen. Das in Wasser wenig lösliche Salz ist hexagonal, P63, mit den Elementarzellparametern: a = 15,904(7), c = 16,67(2) Å und Z = 2.Die Kristallstruktur wurde mit direkten Methoden gelöst und bis zu einem R-Faktor von 0,05 verfeinert. Das um die dreizählige Achse angeordnete Ringanion besitzt daher eine dreizählige Symmetrie. Die gestapelten Ringanionen bilden parallel zur c-Richtung große Kanäle, in die Guanidiniumionen und Wassermoleküle eingebaut sind. Drei der sechs unabhängigen Guanidiniumbaugruppen liegen auf den dreizähligen Achsen.Der Zusammenhalt der Struktur ist auf eine Vielzahl von Wasserstoffbrückenbindungen zurückzuführen, die von den organischen Kationen und den Wassermolekülen ausgehen.
    Notes: The title compound was prepared by ion exchange from the potassium salt, K12P12O36 · 19/2H2O. It represents a second new structural type of [P12O36]12- ring anions. This sparingly water soluble salt is hexagonal, space group P63, with Z = 2 and the cell dimensions: a = 15.904(7), c = 16.67(2) Å. The crystal structure was solved by direct methods and refined to a final R value of 0.050.The ring anion is located around the threefold axis and hence has a threefold symmetry. The stacking of the rings creates large channels, parallel to the c direction, in which the guanidinium groups and the water molecules are located. Three of the six independent guanidinium groups are located on the threefold axes. The cohesion of the structure is performed by the numerous H-bonds generated by the organic cations and the water molecules.

    Notes: Single crystals of caesium iron hydrogen phosphate, Cs3Fe3H15(PO4)9, 2, were prepared hydrothermally by heating caesium iron dihydrogenphosphate, CsFe(H2PO4)4, 1, with a small amount of water. 2 crystallizes orthorhombic, space group Pna21 (No. 33 Int.

Cs+ is placed inside of the channels. Effective Coordination Numbers (ECoN), Mean Fictive Ionic Radii (MEFIR), Charge Distribution (CHARDI) and the Madelung Part of Lattice Energy (MAPLE) are calculated for the title compound.
