Abstract
Hydrazinium(2+) hexafluoroantimonate was prepared by the reaction of N2H6F2 with an excess of SbF5 in anhydrous HF as solvent. The compound was characterized by chemical analysis and vibrational spectra. The X-ray powder photograph was indexed on the basis of a monoclinic cell witha=8.22(2),b=10.04(3),c=9.51(2) Å,β=97.2(2)° andV=780 Å3. The thermal decomposition study of N2H6(SbF6)2 showed that it decomposed to gaseous components through an intermediate, a mixture of N2H5SbF6 and NH4SbF6. In the DSC curve, a strong endothermic effect and medium exothermic and endothermic effects were observed in the range 25–600°C.
