Nickel carbonyl [hsdb]
Nickel tetracarbonyl Ni(CO)4 is an organometallic compound of nickel. Its volatility at room temperature and toxicity have earned the compound the nickname liquid death. This pale-yellow liquid is the principal carbonyl of nickel. It is an intermediate in the Mond process for the purification of nickel and a reagent in organometallic chemistry. Nickel carbonyl is one of the most toxic substances encountered in industrial processes.Nickel is a chemical compound with the atomic number 28. It is found abundantly in nature in laterite ore minerals, such as limonite, garnierite, and pentlandite. Nickel has a biological role and is found in certain enzymes, including urease, hydrogenase, methylcoenzyme M reductase, and carbon monoxide dehydrogenase. (L40, L41, L508)
