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, BiR
3, such as the diphenylbismuthyl group, Ph
2Bi–, found in the ion [Ph
2Bi−(Ge
9)−BiPh
2]
2−
* trivalent bismuth species when considered as ligands, such as the Bismuth tribromide, tribromobismuthyl ligand, Br
3Bi→
In inorganic chemistry Bismuthyl (ion), bismuthyl has been used to describe compounds such as bismuth oxychloride, BiOCl which were assumed to contain the diatomic Bismuthyl (ion), bismuthyl, BiO
+, cation, that was also presumed to exist in aqueous solution.
This diatomic ion is not now believed to exist.
