Sulfur difluoride is an inorganic compound with the chemical formula SF2. It can be generated by the reaction of sulfur dichloride and potassium fluoride or mercury(II) fluoride at low pressures:
- SCl2 + 2 KF → SF2 + 2 KCl
- SCl2 + HgF2 → SF2 + HgCl2
The F-S-F bond angle is 98°, and the length of S-F bond is 159 pm.[1] The compound is highly unstable with respect to FSSF3. 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 from oxygen difluoride and hydrogen sulfide:
- OF2 + H2S → SF2 + H2O
