(H2O)“VIII2F6” and Pyr-VF3:Hydrothermal Synthesis, Structure Determination, and Magnetic Characterization of New Fluorides with the Pyrochlore Type

Small green triangular crystals of a new tridimensional hydrated vanadium(III) fluoride have been hydrothermally prepared in a simple way by heating a mixture of V:HF:H2O in the molar ratio 1:1:50 at 200°C for 3 days. Its structure was solved by X-ray diffraction in the cubic space group Fd3m (No. 2...

Description
Summary:Small green triangular crystals of a new tridimensional hydrated vanadium(III) fluoride have been hydrothermally prepared in a simple way by heating a mixture of V:HF:H2O in the molar ratio 1:1:50 at 200°C for 3 days. Its structure was solved by X-ray diffraction in the cubic space group Fd3m (No. 227) with a=10.4636(2) Å. (H2O)“VIII2F6” presents the structure of the well-known pyrochlore type. The cavities contain water molecules which are lost by heating (T
