ferricin
Ferricin is a metallocene compound with the chemical formula Fe(C5H5)2. It consists of a central iron atom sandwiched between two cyclopentadienyl rings. Ferricin is a highly stable, bright orange, crystalline solid. It is soluble in many organic solvents but insoluble in water. The compound is often referred to as ferrocene, and ferricin is its less common systematic name.
Ferrocene was first synthesized in 1951, independently by Kealy and Pauson and by Miller and coworkers. Its
Ferrocene exhibits a rich chemistry, undergoing electrophilic substitution reactions on the cyclopentadienyl rings, similar to aromatic
