nickel carbonyl

…other important commercial compounds are nickel carbonyl, or tetracarbonylnickel, Ni(CO)₄. This compound, in which nickel exhibits a zero oxidation state, is used primarily as a carrier of carbon monoxide in the synthesis of acrylates (compounds utilized in the manufacture of plastics) from acetylene and alcohols. It was the first of…

…the first simple metal carbonyl, tetracarbonylnickel, Ni(CO)₄, at the end of the 19th century was quickly followed by a series of discoveries in his laboratory and elsewhere showing that most of the d-block metals form neutral homoleptic carbonyls. (The term homoleptic refers to identical groups attached to a central atom.)…

…earliest to be discovered was tetracarbonylnickel, a volatile nickel compound that became the basis of a process for purifying nickel. Metal carbonyls are employed as catalysts in many reactions in the petrochemical industry.

Nickel tetracarbonyl, Ni(CO)₄, a poisonous gas used in the refining of nickel, has 10 electrons provided by the neutral nickel atom and two from each of the four CO ligands, giving 18 electrons in all.

…the case in the compound tetracarbonylnickel, Ni(CO)₄, in which empty π orbitals in the carbon monoxide molecules accept d-orbital electrons from the nickel atom.

Nickel carbonyl, Ni(CO)₄, a liquid at room temperature, is employed in the carbonyl nickel-refining process. Like all other carbonyls, it is poisonous. Nickel subsulfide, Ni₃S₂, is the nickel component of matte involved in pyrometallurgy. Nickel oxide, NiO, is involved in refining processes and also may…
