Ferroalloys
Alloys of iron with other elements made by smelting mixtures of iron ore and the metal ore; e.g., ferrochromium, ferrovandium, ferromanganese, ferrosilicon, etc. They are used in making alloys steels.
Ferrocene,[Fe(C5H5)2]
An organ crystalline solid. It is an example of a sandwich compound, in which an iron (II) ion is coordinated to two cyclopentadienyl ions. The bonding involves overlap of d orbitals on the iron with pi electrons in the cyclopentadienyl ring. The compound metals at 1730 C, is soluble in organic solvents, and can undergo substitution reactions on the rings. It can be oxidized to the blue cation (C5H5)2 Fe+. the systematic name is di-p-cyclopentadienyl iron (II).
