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.[2]
It is characterized by two intense νCO bands in the IR spectrum at 2038 and 2003 cm−1 (hexane solution).[2]
Comparisons of M(CO)5 (M = Fe, Ru, Os)edit
Whereas Fe(CO)5 is completely robust at room temperature, samples of Ru(CO)5 are typically reddish owing to contamination by Ru3(CO)12. The conversion is rapid in solution. Os(CO)5 requires heating to 80 °C to effect conversion to triosmium dodecacarbonyl.[1]
