Ruthenium pentacarbonyl
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. It is of academic interest as an intermediate for the synthesis of metal carbonyl complexes.[1]

Preparation
Ru(CO)5 was originally prepared by carbonylation of ruthenium salts in the presence of a reducing agent.[2] A more recent preparation involves photolysis of triruthenium dodecacarbonyl in the presence of carbon monoxide:[1]
- Ru3(CO)12 + 3 CO ⇌ 3 Ru(CO)5
It is characterized by two intense νCO bands in the IR spectrum at 2038 and 2003 cm−1 (hexane solution).[1]
