Tetrafluorohydrazine

Mass spectrometric study of NF2, NF3, N2F2, and N2F4

“…The relatively large abundance of the m/e=33.5 metastable peak in trans N 2 F 2 made it possible to measure the appearance potential of this ion with good precision. As might be expected on the basis of the statistical theory of mass spectra [ 12 ], the appearance potential is somewhat lower than that of the same ions collected at m/e=47. However, the magnitude of the difference is unexpectedly large.…”

“…Although an extrapolation of the data to lower temperatures is difficult, it seems apparent that the limiting value of the ratio is about 0.08. The change in mass spectrum of N 2 F 4 with temperature, due to decomposition of N 2 F 4 in the ion source, thus accounts for the differences in the mass spectrum of N 2 F 4 reported by different workers [ 2 , 3 , 4 , 12 ]. The data of Loughran and Mader [ 2 ] have already been reinterpreted assuming the presence of NF 2 [ 4 ] in the ion source.…”

Nitrogen–fluorine compounds

“…Colburn and Kennedy in 1958 added another member to this series: dinitrogen tetrafluoride, N 2 F 4 [51,52].…”

Inorganic chemistry

“…l ~~ Direct reduction of nitrogen trifluoride by metals a t 375" leads to tetrafluorohydrazine, N,F,; it boils at -73", has a critical temperature of 36", and has been characterized by analysis and molecular weight. 165 The infrared spectrum of the unusual hydrazine derivative (N2H4)3(HI)2 indicates that it is best formulated as (N,H,+I-),,N2H4. Attempts to prepare anhydrous hydrazonium di-iodide were unsuccessful but led to the new hydrate N2H612,2H20.166 The hydrazine-NN-disulphonate (9) and -trisulphonate (10) were prepared by treating potassium imidodisulphonate (8) with hydroxylamine-0-sulphonic acid and then with pyridine-sulphur trioxide :…”
