The molecular formula of ferrocene is Fe (C5H5)2, and it was discovered in the 1951. After the discovery of ferrocene, an entire new class of compounds arose called the d-block organometallic compounds. In ferrocene, the carbon atom is bonded to a metal atom such as an atom of Iron (Fe). There are two rings on either side of the atom of iron.
It is used as a fuel additive in petrol engines and in the pharmaceutical industry. Anticancer medications are prepared with ferrocene salts.Learn more about States of Matter
