Chromium tetrafluoride oxide

The reaction of equimolar amounts of CrOF4 and CsF at 100°C yields orange-brown Cs+CrOF5 , which was characterized by infrared spectroscopy [306], Chromium tetrafluoride oxide combines with NOF in a 1 1 mole ratio to yield the stable, pink solid adduct NO+CrOF5 which was characterized by vibrational spectroscopy [304]. Controlled pyrolysis of NO+CrOF5 yields a mixture of NO+CrOF 5 and NO+CrOF5 -nCrOF4 [304], The infrared spectrum of this mixture...

Chromium(VI) tetrafluoride oxide CrF40 was first synthesized via fluor-ination of either metallic chromium or CrOj, and the route has been modified to use CrOj at lower temperature. Very recently, fluorination of Cr02F2 with KrF2 in anhydrous HF was reported. However, this route requires the use of a rather exotic fluorinating agent. The procedure described below involves the catalytic fluorination of Cr02F2 in the presence of CsF. 

Chromium(VI) tetrafluoride oxide (mp 55°) is a dark red solid that exists in equilibrium with its purple vapor at 25°. It is highly soluble in BrFj, SO2CIF, and anhydrous HF. The gas-phase IR spectrum has a very strong characteristic absorption band at 755 cm assigned to 77(6). Medium absorption bands are at 1028 Vi(Ai) and at 696 72( 1)cm . The mass spectrometric cracking pattern is CrOF, CrOF, CrOF, CrF, CrOF", CrO, and Cr. ...
