(Norbornadiene)molybdenum tetracarbonyl is the

organomolybdenum compound Organomolybdenum chemistry is the chemistry of chemical compounds with Mo-C bonds. The heavier group 6 elements molybdenum and tungsten form organometallic compounds similar to those in organochromium chemistry but higher oxidation states tend to ...

with the formula (C₇H₉)Mo(CO)₄. Structurally, the compound consists of the

norbornadiene Norbornadiene is an organic compound and a bicyclic hydrocarbon. Norbornadiene is of interest as a metal-binding ligand, whose complexes are useful for homogeneous catalysis. It has been intensively studied owing to its high reactivity and distin ...

bonded to a Mo(CO)₄ fragment. The compound is a yellow, volatile solid. It is prepared by thermal or photochemical substitution of

molybdenum hexacarbonyl Molybdenum hexacarbonyl (also called molybdenum carbonyl) is the chemical compound with the formula Mo(CO)6. This colorless solid, like its chromium, tungsten, and seaborgium analogues, is noteworthy as a volatile, air-stable derivative of a metal ...

. The compound was originally examined as a potential

antiknock agent An antiknock agent (also: knock inhibitor) is a gasoline additive used to reduce engine knocking and increase the fuel's octane rating by raising the temperature and pressure at which auto-ignition occurs. The mixture known as gasoline or petrol, ...

. (Norbornadiene)molybdenum tetracarbonyl is a precursor to other derivatives of the type L₂Mo(CO)₄. This conversion exploits the lability of the diene ligand: :(C₇H₉)Mo(CO)₄ + 2 L → C₇H₉ + L₂Mo(CO)₄
