Chloroiodide

Chloroiodide is a chemical term that can refer to a few different things, primarily an anion or a compound containing chlorine and iodine. The most common chloroiodide species is the anion [ICl2]−. This anion consists of one iodine atom bonded to two chlorine atoms. It is a linear species with the iodine atom at the center. This chloroiodide anion is often found as a counterion in various salts.

Another context for chloroiodide is in referring to compounds that contain both chlorine and iodine, not necessarily as a discrete anion. For example, some interhalogen compounds might be loosely described as chloroiodides. However, the term is most specifically associated with the [ICl2]− anion.

The synthesis of salts containing the chloroiodide anion typically involves reactions between iodine, chlorine, and a suitable cation source. These compounds are generally soluble in polar solvents. The properties of chloroiodide salts vary depending on the cation they are paired with. Research into chloroiodide compounds often focuses on their structural characteristics, reactivity, and potential applications in areas such as catalysis or as sources of iodine and chlorine.
