On the System Zn/Mo/O. I. Phases and Properties of Ternary Zinc Molybdates; Crystal Structure of Zn3Mo2O9Several ternary compounds are known in the Zn/Mo/O-system. The phases ZnMoO4, Zn2Mo3O8 and Zn3Mo2O9 are stable at 900°C. The coexistence ranges are shown in the ternary phase diagram. The structure of Zn3Mo2O9 has been determined by single crystal X-ray diffraction. The compound crystallizes in the monoclinic space group P21/m (a = 7,757(1) Å, b = 7,132(1) Å, c = 8,370(2) Å, β = 117,40(1)º, Z = 2).
Notes:
Im System Zn/Mo/O sind mehrere ternäre Phasen bekannt. Bei 900°C sind die Phasen ZnMoO4, Zn2Mo3O8 und Zn3Mo2O9 stabil. Die Koexistenzgebiete sind am ternären Phasendiagramm dargestellt. Die Strukturbestimmung von Zn3Mo2O9 erfolgte mit Röntgenbeugung an Einkristallen. Die Verbindung kristallisiert in der monoklinen Raumgruppe P21/m (a = 7,757(1) Å, b = 7,132(1) Å, c = 8,370(2) Å, β = 117,40(1)º, Z = 2).
