Thionyl fluoride (CAS NO.7783-42-8) is also called Fluorure de thionyle ; Fluorure de thionyle [French] ; Sulfur difluoride monoxide ; Sulfur difluoride oxide ; Sulfurous oxyfluoride ; Thionyl difluoride . Thionyl fluoride (CAS NO.7783-42-8) is the inorganic compound with the formula SOF2. This colourless gas is mainly of theoretical interest, but it is a product of the degradation of sulfur hexafluoride, an insulator in electrical equipment. The molecule adopts a pyramidal structure, with C2v symmetry. The S-O and S-F distances are 1.42 and 1.58 A, respectively. The O-S-F and F-S-F angles are 106.2 and 92.2°, respectively. Thionyl chloride and thionyl bromide have similar structures, although these compounds are liquid at room temperature. Mixed halides are also known, such as SOClF. Thionyl fluoride (CAS NO.7783-42-8) can react with water. It will decompose on heating. |
