Dicarbonylcyclopentadienylcobalt（Cat No.:M062037）, commonly known as cobaltocene dicarbonyl or CpCo(CO)₂, is an organocobalt compound consisting of a cobalt(I) center coordinated to a cyclopentadienyl (Cp) ligand and two carbonyl (CO) groups. This 18-electron complex is a volatile, orange-yellow crystalline solid used in organometallic chemistry as a precursor for various cobalt-based catalysts and complexes. The compound is reactive toward ligand substitution and oxidative addition, making it valuable in homogeneous catalysis and materials research. It is air-sensitive and must be handled under inert conditions. CpCo(CO)₂ serves as a model compound for studying transition metal-ligand bonding interactions.
