Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
- 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:
- OF2 + H2S → SF2 + H2O
