“…The analogous reaction of [O 2 ][SbF 6 ] with Na[HCB 11 Cl 11 ] in liquid SO 2 at –60 °C did not lead to the desired metathesis product in accord with thermodynamic considerations discussed above 15. The solution turned black immediately after mixing the reactants at low temperature.…”

The thermodynamic stability of the [HCB 11 Cl 11 ]salts of the cationic one-electron oxidizers [NO] + and [O 2 ] + was estimated by Born-Haber-Fajans cycles based on quantum-chemical calculations and lattice enthalpy estimations. [NO][HCB 11 Cl 11 ] is predicted to be a stable compound, whereas [O 2 ][HCB 11 Cl 11 ] should decompose into O 2 and the HCB 11 Cl 11 · radical. Consequently, [NO][HCB 11 Cl 11 ] can be prepared by metathesis reaction from Na[HCB 11 Cl 11 ] and [NO][BF 4 ] in liquid sulfur dioxide, while attempts to synthesize [O 2 ][HCB 11 Cl 11 ] failed. [NO][HCB 11 Cl 11 ] has been fully characterized

“…13,14 The reactivity of azides toward various dioxygenyl salts was investigated in the scope of research on highly energetic materials. 15 The first dioxygenyl salt, O 2 PtF 6 , was reported by Bartlett and Lohmann in 1962. 16,17 It was initially erroneously identified as PtOF 4 , 18 which is not surprising given that the [O 2 ] + cation as the [PtF 6 ] − anion were unknown at that time.…”

By treating gaseous, liquid, or solid fluorides with UV-photolyzed O2/F2 mixtures and by treating solid oxides with UV-photolyzed F2 (or O2/F2 mixtures) in liquid anhydrous HF at ambient temperature, we investigated the possibility of the preparation of O2MIIIF4 (M = B, Fe, Co, Ag), O2MIVF5 (M = Ti, Sn, Pb), (O2)2MIVF6 (M = Ti, Ge, Sn, Pb, Pd, Ni, Mn), O2MIV 2F9 (M = Sn), O2MVF6 (M = As, Sb, Au, Pt), O2MV 2F11 (M = Pt), O2MVIF7 (M = Se), (O2)2MVIF8 (M = Mo, W), and O2MVIIF8 (M = I). The approach has been successful in the case of previously known O2BF4, O2MF6 (M = As, Sb, Au; Pt), O2GeF5, and (O2)2(Ti7F30). Novel compounds O2GeF5·HF, α-O2Sn2F9 (1-D), and the HF-solvated and nonsolvated forms of β-O2Sn2F9 (2-D) were synthesized and their crystal structures determined using single-crystal X-ray diffraction. The crystal structures of all of these materials arise from the condensation of octahedral MF6 (M = Ge, Sn) units. The anion in the crystal structure of O2GeF5·HF is comprised of infinite ([GeF5]−)∞ chains of GeF6 octahedra that share common vertices. The HF molecules and O2 + cations are located between the chains. The crystal structure of α-O2SnF9 (1-D) is constructed from [O2]+ cations and polymeric ([Sn2F9]−)∞ anions which appear as two parallel infinite chains comprised of SnF6 units, where each SnF6 unit of one chain is connected to a SnF6 unit of the second chain through a shared fluorine vertex. The single-crystal structure determination of [O2][Sn2F9]·0.9HF reveals that it is comprised of two-dimensional ([Sn2F9]−)∞ grids with [O2]+ cations and HF molecules located between them. The 2-D grids have a wavelike conformation. The ([Sn2F9]−)∞ layer contains both six- and seven-coordinated Sn(IV) atoms that are interconnected by bridging fluorine atoms. A new, more complex [O2]+ salt, O2[Hg(HF)]4[SbF6]9, was prepared. In its crystal structure, the Hg atoms bridge to SbF6 units to form a 3-D framework. The O2 + cations are located inside the voids while the HF molecules are bound to Hg atoms through the F atom. Attempts to prepare several chlorine analogues of O2 + fluorine salts (i.e., O2TiCl5 and O2MCl6 (M = Nb, Sb)) failed.
