Sulfonium

Structure of (CH3)3S+. The C-S-C angles are 102° and C-S bond distance is 177 picometers.[1]

In organic chemistry, a sulfonium ion, also known as sulphonium ion or sulfanium ion, is a positively-charged ion (a "cation") featuring three organic substituents attached to sulfur. These organosulfur compounds have the formula [SR3]+. Together with a negatively-charged counterion, they give sulfonium salts. They are typically colorless solids that are soluble in organic solvent.[2][3]
