metalocene
A metalocene is a class of organometallic compounds that contain a metal atom coordinated to a cyclopentadienyl (Cp) ligand. The term "metalocene" is derived from the Greek word "metallon," meaning metal, and "cyclopentadiene," the precursor to the Cp ligand. The most well-known example of a metalocene is ferrocene, which contains an iron atom coordinated to two Cp ligands. Metalocenes are significant in organometallic chemistry due to their unique structural and electronic properties.
The general formula for a metalocene is M(Cp)2, where M represents a metal atom. The Cp ligand
Metalocenes have a wide range of applications in various fields, including catalysis, materials science, and medicine.
Despite their importance, metalocenes are also known for their toxicity, and their handling requires careful consideration
