[Chemical Properties]

WHITE TO LIGHT YELLOW CRYSTALLINE POWDER
[Health Hazard]

Molybdenum hexacarbonyl is a highly toxicsubstance. It is listed in Toxic SubstanceControl Act. Acute symptoms includeheadache, dizziness, nausea, vomiting, andfever. Because of its low vapor pressure,the risk of exposure of this compound,however, by inhalation is lower than thatfrom the volatile tetra- or pentacoordinatedmetal carbonyls. Ingestion of the compoundcan cause death. Absorption of its solutionthrough skin may cause severe poisoning,manifesting the same effects as those fromother routes of exposure.
[Fire Hazard]

It reacts violently with strong oxidizers. Contact with concentrated acids is expected to be violent. Its solutions are susceptible to detonate spontaneously (Owen 1950). Ethereal solutions of this compound can explode on extended storage (Bretherick 1995).
[Purification Methods]

Sublime it in a vacuum before use [Connor et al. J Chem Soc, Dalton Trans 511 1986]. TOXIC.
