Subhalide


In chemistry, subhalide usually refers to inorganic compounds that have a low ratio of halide to metal, made possible by metal–metal bonding, sometimes extensive. Many compounds meet this definition.

Examples

The normal halide of boron is boron trifluoride|. Boron forms many subhalides: several, including diboron tetrafluoride|; also BF. Aluminium forms a variety of subhalides. For gallium, adducts of are known. Phosphorus subhalides include diphosphorus tetraiodide|,, and . For bismuth, the compound originally described as bismuth monochloride was later shown to consist of clusters and chloride anions. There are many tellurium subhalides, including tritellurium dichloride|, ditellurium bromide|, and two forms of TeI.
