Sulfur difluoride is aninorganic compound with the chemical formula SF2. It can be generated by the reaction ofsulfur dichloride andpotassium fluoride ormercury(II) fluoride at low pressures:
The F−S−Fbond angle is 98°, and the length of S−F bond is 159 pm.[1] The compound is highly unstable, dimerising toFSSF3. This unsymmetrical isomer of S2F4 is proposed to arise via insertion of SF2 into the S−F bond of a second molecule SF2:[2]
It can also be formed fromoxygen difluoride andhydrogen sulfide:[citation needed]
