Characterisation of chromium(VI) oxide tetrafluoride, CrOF4, and caesium pentafluoro-oxochromate(VI) Cs[CrOF5]

Abstract

The title compounds have been characterised by elemental analyses, i.r. And u.v.–visible spectroscopy, and some of their reactions are described. Matrix isolation studies on CrOF4 show characteristic i.r. absorptions at 1 027.7 and 746.3,741.6 cm–1 in nitrogen matrices, which are assigned as the A1(Cr[double bond, length as m-dash]O) and E(Cr–F) modes respectively of the C4v monomer. Chromium isotope fine structure and relative intensity estimates suggest a bond angle of ca. 106° for OCrF. The electronic spectrum of matrix-isolated CrOF4 shows prominent charge-transfer bands at 40 000 and 27 000 cm–1.
