Rhodium carbonyl chloride (Cat No.: M064755), typically represented as Rh(CO)₂Cl, is an organometallic compound containing rhodium in the +1 oxidation state, coordinated to carbonyl (CO) ligands and a chloride ion. It often exists as a dimer, [Rh(CO)2Cl]2[Rh(CO)₂Cl]_2[Rh(CO)2​Cl]2​, featuring bridging chloride ligands. This compound is a valuable precursor in homogeneous catalysis and organometallic synthesis. It is used in reactions such as hydroformylation, hydrogenation, and carbonylation. Due to its reactive metal center and labile ligands, it plays a key role in developing rhodium-based catalytic systems.
