The reaction of hydrazinium difluoride and TaF5 in 66% hydrofluoric acid water solution resulted in the formation of rather unusual (N2H6)3TaF8TaF7HF2 compound. Similar procedure started from a TaF5NaF mixture performed in 35% HF water solution resulted in the formation of a Na7TaF8(TaF7)2 compound. Synthesis, crystal structures and Raman spectra of these new compounds are reported in this communication
