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:
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. This diatomic ion is not now believed to exist.
