Novel synthesis, characterization and thermal degradation of hydrazinium hexafluorophosphate

Abstract

Hydrazmium hexafluorophosphate has been synthesised for the first timc in quantitative yields in a direct reaction between ammonium hexafluorophosphate and hydrazlnc hydrate. Chemical analysis and infrared spcctroscopy characterzes the white crystalline solid as N2H5-PF6 Thermal decomposition in has has been studied by TG and DTA techniques. A stepwise composition is observed with an intermediate formation of NH4 PF6 . The final products are, however, all gases, ammoma, hydrogen fluonde and phosphate pentafluoride which makes it an interesting species for thermal reaction studies.
