    Description / Table of Contents: Die Kristallstruktur des mit KNbP2O8 isotypen Molybdän(V)-diphosphates KMoP2O8Ein neues Molybdän(V)-diphosphat, KMoP2O8, ist dargestellt worden. Die Einkristall-Strukturanalyse hat Isotypie mit KNbP2O8 ergeben; Raumgruppe P21/n; a = 5,0862(4), b = 11,720(1), c = 11,486(1) Å, β = 90,91(1)°. Die Kristallstruktur dieser Verbindung wird mit denen anderer Molybdän(V)-diphosphate verglichen. Die Tunnelstruktur wird durch [MP2O8]∞-Bänder entlang ā beschrieben, was die enge Beziehung zum Titanphosphat NaTiP2O7 zeigt. Die Existenz einer freien Spitze sowohl an jedem Mo06-Oktaeder als auch an jeder P2O7-Gruppe ist deutlich und erlaubt eine große Flexibilität der Struktur.
    Notes: A new molybdenum(V) diphosphate KMoP2O8 has been isolated. The single crystal X-ray diffraction study of this phase has shown that it is isotypic with KNbP2O8. It crystallizes in the P21/n space group a = 5.0862(4), b = 11.720(1), c = 11.486(1) Å, β = 90.91(1)°. The structure of this phase is compared with those of other molybdenum(V) diphosphates. This tunnel structure is described in terms of [MP2O8]8∞ ribbons running along ā, showing close relationships with the titanophosphate NaTiP2O7. The existence of one free apex for each MoO6 octahedron and each P2O7 group, respectively, is emphasized, allowing a great flexibility of the structure.
