  A convenient synthesis of CrF6 from CrO3 and F2(170 °C/25 atm/72 h) is described; it is characterized by matrix-isolation i.r. spectroscopy, and using this technique there is wvidence that molecular CrF6 undergoes thermal decomposition to CrF4 at low pressures.

  描述了从CrO 3和F 2（170°C / 25 atm / 72 h）方便地合成CrF 6的方法。它的特征在于基体隔离红外光谱，并且使用这种技术可以证明分子CrF 6在低压下会热分解为CrF 4。

  The reactions of the fluoride‐ion donor, XeF6, with the fluoride‐ion acceptors, M′OF4 (M′=Cr, Mo, W), yield [XeF5]+ and [Xe2F11]+ salts of [M′OF5]− and [M2O2F9]− (M=Mo, W). Xenon hexafluoride and MOF4 react in anhydrous hydrogen fluoride (aHF) to give equilibrium mixtures of [Xe2F11]+, [XeF5]+, [(HF)n F]−, [MOF5]−, and [M2O2F9]− from which the title salts were crystallized. The [XeF5][CrOF5] and [Xe2F11][CrOF5]

  motif among the known oxyfluoro-anions of Group 6. The X-ray structures show that [XeF5 ]+ and [Xe2 F11 ]+ form ion pairs with their respective anions by means of Xe- - -F-Cr bridges. Quantum-chemical calculations were carried out to obtain the energy-minimized, gas-phase geometries and the vibrational frequencies of the anions and their ion pairs and to aid in the assignments of their Raman spectra
