Product Description

Property

CAS No.: 13814-25-0 Formula: F2S Molecular Weight: 70.06180

Description

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. 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:
It can also be formed from oxygen difluoride and hydrogen sulfide:
OF2 + H2S → SF2 + H2O
