    Description / Table of Contents: Kristallstruktur des Calciumpolyphosphates [Ca2(PO3)4]xβ-Calciumpolyphosphat kristallisiert in der monoklinen Raumgruppe P21/c mit den Gitterkonstanten a = 6,999, b = 7,717, c = 16,944 Å, β = 90,44°. Die Full-Matrix-Verfeinerung mit Einheitsgewicht führte zu R = 0,022. Auf die Periode der Anionenkette kommen 4 Tetraeder, Kettenrichtung ist x. Die Kationen-Polyeder bilden Doppelketten, ebenfalls parallel x, in denen die Polyeder über gemeinsame Flächen und Kanten verknüpft sind.
    Notes: β-Calciumpolyphosphate crystallizes in the monoclinic space group P21/c, unit cell a = 6.999, b = 7.717, c = 16.944 Å, β = 90.44°. Full matrix refinement with unit weight lead to R = 0.022. The period of the anion chain amounts to 4 tetrahedra, chain direction is x. The cation polyhedra form double chains, also parallel x, in which the polyhedra are linked by common faces and edges.
