Ruthenium pentacarbonyl is the organoruthenium compound with the formula Ru(CO)5. It is a colorless, light-sensitive liquid that readily decarbonylates upon standing at room temperature. The is of academic interest as an intermediate for the synthesis of metal carbonyl complexes.
Ru(CO)5 was originally prepared by carbonylation of ruthenium salts in the presence of a reducing agent. A more recent preparation involves photolysis of triruthenium dodecacarbonyl in the presence of carbon monoxide:
