Structural data on potassium dioxydifluorobromate (V) KBrO2F2

Abstract
The x‐ray powder pattern of potassium dioxydifluorobromate KBrO2F2 is given and is indexed in an orthorhombic cell with the parameters a=7.28±0.02, b=6.75±0.02, c=7.87±0.02 Å. A set of force constants calculated from infrared and Raman data is given for both the BrO2F2 ion and BrO2F.
