oxohalide

Also known as molecular oxohalides

In chemistry, oxohalides or oxyhalides are a group of chemical compounds with the chemical formula , where X is a halogen, and A is an element different than O and X. Oxohalides are numerous. Molecular oxohalides are molecules, whereas nonmolecular oxohalides are polymeric. Some oxohalides of particular practical significance are phosgene (COCl2), thionyl chloride (SOCl2), and sulfuryl fluoride (SO2F2).
