Bismuthyl

Bismuthyl means a chemical species formally derived from the element bismuth and can refer to substituents bonded to the rest of a molecule through a bismuth atom, including:

* derivatives of bismuthanes, BiR3, such as the diphenylbismuthyl group, Ph2Bi–, found in the ion [Ph2Bi−(Ge9)−BiPh2]2−
* trivalent bismuth species when considered as ligands, such as the tribromobismuthyl ligand, Br3Bi→

In inorganic chemistry bismuthyl has been used to describe compounds such as BiOCl which were assumed to contain the diatomic bismuthyl, BiO+, cation, that was also presumed to exist in aqueous solution.[1] This diatomic ion is not now believed to exist.[2]
