Nickel tetracarbonyl
Nickel tetracarbonyl (pronunciation: /ˈnɪkəl ˌtɛtrəkɑːrˈbɒnaɪl/) is a chemical compound with the formula Ni(CO)4. This pale-yellow liquid is the principal carbonyl of nickel. It is an intermediate in the Mond process for producing very high-purity nickel and a reagent in organometallic chemistry, although the Mond Process has fallen out of common usage due to the health hazards in working with the compound.
Etymology
The term "Nickel tetracarbonyl" is derived from the elements that make up the compound. "Nickel" is from the Swedish "kopparnickel", meaning "copper-colored ore", and "tetracarbonyl" is from the Greek "tetrakis", meaning "four times", and "carbonyl", a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O.
Chemical Properties
Nickel tetracarbonyl is a volatile, highly toxic liquid that is soluble in organic solvents. It is not stable at room temperature, decomposing to give carbon monoxide and nickel metal. The compound is used in organometallic chemistry as a source of nickel.

Health Hazards
Exposure to nickel tetracarbonyl can result in severe health hazards, including lung and kidney damage, and neurological effects. It is classified as a human carcinogen.
