Antimony heterocycles

Stibole is a heterocyclic organic compound, a five-membered ring with the formula C4H4SbH. It is classified as a metallole. It can be viewed as a structural analog of pyrrole, with antimony replacing the nitrogen atom of pyrrole. Stibole itself has not been isolated, but many substituted derivatives have been synthesized. They are called stiboles.

Stibabenzene is an organic chemical compound. Stibabenzene has the chemical formula . The molecule is a derivative of benzene, with one of the carbon atoms in the 6-membered ring replaced by an antimony (Sb) atom. Stibabenzene is a molecule that is considered to be an organoantimony compound due to it containing carbon, hydrogen, and antimony atoms.
