Cobalt tricarbonyl nitrosyl is the organocobalt compound with the formula Co(CO)3(NO). It is a dark red volatile oil that is soluble in nonpolar solvents. The compound is one of the simplest metal nitrosyls. It is highly toxic, reminiscent of the same property for nickel tetracarbonyl.

## Synthesis and reactions

Cobalt tricarbonyl nitrosyl is prepared by the treatment of dicobalt octacarbonyl with nitric oxide:[1]

Co2(CO)8 \+ 2 NO → 2 Co(CO)3NO + 2 CO

Many other methods have been developed.

The complex undergoes substitution readily by Lewis bases such as tertiary phosphines and isocyanides, concomitant with loss of CO.[2]
