1 Iron Complexes in Organic Chemistry

Iron(III) generally is a harder Lewis acid than iron(II) and thus binds to hard Lewis bases. Iron(0) mostly coordinates five or six ligands with trigonal bipyramidal and octahedral geometry. Iron(–II) is tetrahedrally coordinated. Iron in low oxidation states is most interesting for organometallic chemistry and in particular for iron

Iron oxide (Fe2O3) - Structure, Molecular Mass, Properties & Uses

They are ferrous oxides. Thus, Fe2O3 is a simple oxide where Fe is only + 3 in the oxidation state thus Fe3O4 is a mixed oxide where Fe is present in both + 2 and + 3 oxidation states. However, we compose Fe3O4 as FeO. Fe2O3 is written as iron oxide (II) while Fe3O4 is written as iron oxide (II, III).
