(N2H6)3TaF8TaF7HF2and Na7TaF8(TaF7)2: Novel fluoride tantalates with different isolated anionic polyhedra

, p. 13 - 17 (2017)
The reaction of hydrazinium difluoride and TaF5in 66% hydrofluoric acid water solution resulted in the formation of rather unusual (N2H6)3TaF8TaF7HF2compound. Similar procedure started from a TaF5[sbnd]NaF mixture performed in 35% HF water solution resulted in the formation of a Na7TaF8(TaF7)2compound. Synthesis, crystal structures and Raman spectra of these new compounds are reported in this communication. The main feature of both compounds is the presence of discrete TaF83?and TaF72?anions in their crystal structures, which was also confirmed by Raman spectroscopy.

Chemical interaction of transition metals (Mo, W, Ta, Nb, and Ti) with a tetrafluoroethylene-vinylidene fluoride (TFE-VDF) copolymer (21 mol % TFE + 79 mol % VDF) has been studied by differential scanning calorimetry (DSC) and mass spectrometry. The DSC c

A new value of the enthalpy of formation of tin difluoride was used to calculate the thermodynamic parameters of reactions of SnF2 with elemental substances and several metal oxides. SnF2 can act as an oxidizer and is useful for the synthesis of higher fluorides of group III-V transition metals, including those that have previously been prepared only by reactions with elemental fluorine (TiF4, NbF5, TaF5). The fact that such reactions occur was verified experimentally.
