Precautions

  1. It should be stored in a sealed container at 2-8℃, in a dry, dark place, under the protection of an inert gas.

  2. Carbonyl compounds may release CO or other volatile substances; protective gloves, goggles, and protective clothing should be worn during handling.

  3. Osmium carbonyl is generally slightly harmful to water bodies. Do not expose undiluted or large quantities of the product to groundwater, waterways, or sewage systems.

  4. It should be treated in accordance with the regulations for heavy metal and organometallic waste, and should not be discharged at will.

FAQ

1. Why is osmium carbonyl frequently used in the study of metal carbonyl clusters?

Because its cluster structure is well-defined (3 osmium groups, 12 carbonyl groups), and it has good compatibility with ligand substitution and intra-cluster reaction studies, making it a typical model for metal-metal bonding and carbonyl chemistry research.


2. How to store Os3(CO)12 to maintain its activity?

It is recommended to store it in a sealed container under low temperature (2-8°C) and inert gas protection in a dark, dry environment; during operation, try to do so in a glove box or under dry, oxygen-free conditions.
