Sulfur tetrafluoride Gas is a colorless gas with a distinct sulfurous odor. It is highly toxic by inhalation and is highly irritating to the skin, eyes and mucous membranes. It reacts violently with water and acids, producing toxic fluoride and sulfur oxide fumes and acidic solutions. Sulfur tetrafluoride is heavier than air.

The sulfur in SF4 is in the formal +4 oxidation state. Sulfur has a total of six valence electrons, two of which form lone pairs. Therefore, the structure of SF4 can be predicted using the principles of VSEPR theory: it is a seesaw shape with the S at the center. One of the three equatorial positions is occupied by non-bonding lone pair electrons. Therefore, this molecule has two different types of F ligands, two axial and two equatorial.

We offer a variety of Specialty gas packages to meet a wide range of needs. We have the right gas from the right packaging and delivery source for you.
