Modification of an NF3 film by sub-excitation electrons
Tegeder, Petra,Illenberger, Eugen
, p. 401 - 406 (2001)
By applying the IRAS technique (infrared-absorption-reflection spectroscopy) and electron stimulated desorption (ESD) of negative ions we demonstrate that a 10 monolayer (ML) film of NF3 is degraded in the course of low-energy electron irradiation in the range 0-5 eV which is far below the electronic excitation of NF3. Degradation is accompanied by the desorption of F- fragment ions from the film and formation of NF2 radicals and N2F4 molecules in the film. The energy dependence of the degradation cross-section follows that for resonant (dissociative) electron attachment in the low-energy region (≈0-5eV) and increases above 6 eV. We therefore identify (dissociative) electron capture at low energy as the only initial reaction responsible for the chemical changes in the NF3 film.
Nitrosodifluoroamine, F2N2O

Nitrous oxide, N2O, was observed to react with F2 under UV irradiation at -196 °C to form initially F2N2O which in accord with earlier reports from the literature decomposes above -140 °C to form N2F4 and NO. The apparently different reaction behavior of N2O toward H radicals (→H2O+N2) and F radicals (→F2N2O→N2F4+NO) can be accounted for by thermodynamic considerations [average bond energies (kcal mol-1): O-H (114.2)>N-H (93.3); N-F (66.4)>O-F (44.7)]. A reaction mechanism for the formation and decomposition of F2N2O from N2O and F2 (present study) and from N2F4 and NO has been suggested using valence bond considerations. The structure of F2N2O was fully optimized at the electron correlated MP2(FULL)/cc-pVTZ level of theory and was shown to possess C1 symmetry. A frequency analysis clearly shows the C1 structure to represent a true minimum (NIMAG = 0), whereas the earlier reported planar Cs structure was shown to represent a first-order transition state (NIMAG = 1).
Vibrational spectra of AuF5 complexes with nitrogen fluorides and oxofluorides

Vibrational spectra and structural features of AuF5 complexes with nitrogen fluorides (NF3, N2F4) and oxofluorides (FNO, NF3O) are investigated. Vibrational frequency assignment in the solid phase and
Condensed phases of difluoramine and its alkali-metal fluoride adducts
Christe, Karl O.,Wilson, Richard D.
, p. 920 - 925 (2008/10/08)
Infrared and Raman spectra of HNF2 and DNF2 in the liquid and the solid phases show that the compounds are associated through hydrogen bridges between the nitrogen atoms. Raman spectra of the KF, RbF, and CsF adducts and infrared spectra of the RbF adduct of difluoramine are interpreted in terms of strongly hydrogen-bridged [F?HNF2]- anions. For the CsF and RbF adducts evidence was obtained for the existence of a distinct second modification of the [F?HNF2]- anion with a significantly stronger hydrogen bridge. The reactions of KF·HNF2 with TeF5OF, OF2, FONO2, and FOClO3 were studied and resulted in the fluorination of HNF2 to HF and N2F4.
Xenon-nitrogen bonds. The synthesis and characterization of [imidobis(sulfuryl fluoride)]xenon(II) derivatives Xe[N(SO2F)2]2, FXeN(SO2F)2, and [(FSO2)2NXe]2F+

The synthesis and characterization of three compounds containing xenon-nitrogen bonds are described. The novel compounds Xe[N(SO2F)2]2 and FXeN(SO2F)2 are obtained by low-temperature reactions of XeF
Some chemistry of difluoraminocarbonyl chloride. A new route to perfluorourea
Wright, Kenneth J.,Shreeve, Jean'ne M.
, p. 77 - 80 (2007/10/12)
Improved yields of NF2C(O)Cl are obtained by short-term (4-6 hr) photolysis of N2F4 with oxalyl chloride. Reactions of NF2C(O)Cl with AgCN, AgNCS, AgNCO, Hg(SCF3)2 and Hg(ON(CF3)2)2 give the new difluoraminocarbonyl pseudohalides NF2C(O)CN, NF2C(O)NCS, NF2C(O)NCO, NF2C(O)SCF3, and NF2C(O)ON(CF3)2. With excess of either Ag2O at 0° or HgO at -78°, NF2C(O)Cl is converted to (NF2)2CO and CO2 in nearly quantitative yield. Chlorocarbonyl fluorosulfate results when NF2C(O)Cl is mixed with S2O6F2 or BrOSO2F.
