In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Electrochemical Parameterization in Sandwich Complexes of the First Row Transition Metals, published in 1996-02-14, which mentions a compound: 1273-73-0, Name is Bromoferrocene, Molecular C10BrFe, Quality Control of Bromoferrocene.
Applying the ligand electrochem. parameter approach to sandwich complexes and standardizing to the FeIII/FeII couple, the authors obtained EL(L) values for over 200 π-ligands. Linear correlations exist between formal potential (E°) and the ∑EL(L) for each metal couple. In this fashion, the authors report correlation data for many first row transition metal couples. The correlations between the EL(L) of the substituted π-ligand and the Hammett substituent constants (σp) are also explored.
