Ba2W03F4 and Other Oxidefluorides of Tungsten and MolybdenumNew oxidefluorides are obtained in form of colourless powders by heating appropriate mixtures of the binary constituents: Ba2WO3F4 (a = 11.51 b = 9.38 c = 7.19 Å, β = 126.2° Z = 4, monoclinic, new type of structure) and the isotypic Ba2MoO3F4 (a = 11.46 b = 9.36 c = 7.24 Å, β = 126.3°, Z = 4) as well as PbWO3F2 (a = 20.86 c = 14.75 Å, Z = 64, tetragonal, isotypic with SrAlF5) and Pb3W2O6F6 (a = 20.65 c = 14.77 Å, tetragonal, Z = 24, isotypic with Sr3Fe2F12).
Notizen:
Neu dargestellt wurde Ba2WO3F4, nach Pulverdaten monoklin mit a = 11,51, b = 9,38 und c = 7,19 Å, β = 126,2°, Z = 4, eigener Typ, damit isotyp Ba2MoO3F4, a = 11,46, b = 9,36 und c = 7,24 Å, β = 126,3 (Pulverdaten) sowie PbWO3F2 (isotyp mit tetragonalem SrAlF5: a = 20,86, c = 14,75 Å, Z = 64, Pulverdaten) und Pb3W2O6F6, tetragonal, isotyp mit Sr3Fe2F12 (a = 20,65, c = 14,77 Å, Z = 24), jeweils aus den binären Komponenten. Alle neuen Oxidfluoride sehen farblos aus.
