Iodinebonded

Iodinebonded is a term used in chemistry to describe chemical species in which iodine plays a defining role in the bonding framework of the molecule or material. The descriptor is not a formal name for a single class of compounds but a way to emphasize iodine-centered bonding interactions, including covalent bonds, halogen bonds, and polyiodide networks.

Iodinebonded systems encompass several bonding modes. Covalent bonds such as carbon–iodine (I–C) or metal–iodine (M–I) bonds are common in organoiodine compounds and metal iodides. Halogen bonding can involve iodine acting as a Lewis acid, forming I···X interactions with electronegative atoms or groups. Polyiodide structures feature networks of iodine atoms, as seen in I3− and related species, which can exist in solid salts or solution. In some contexts, iodine participates in coordinate or charge-transfer interactions with metals, polymers, or aromatic systems, contributing to electrical, optical, or catalytic properties.

Representative examples include organoiodines like iodoalkanes and iodoarenes, polyiodide salts in solution or solid materials, and inorganic iodides such as metal iodides. Iodinebonded concepts also appear in conductive polymers and other materials where iodine-centered interactions influence performance, stability, or reactivity. In synthesis, iodine-containing reagents promote iodination and related transformations by forming iodine-centered bonds during reaction steps.

The term is primarily used descriptively in literature to group discussions of iodine-related bonding phenomena rather than to denote a single standardized category. It is most often encountered in discussions of organoiodine chemistry, halogen bonding, and polyiodide chemistry.
