Chromium hexacarbonyl (IUPAC name: hexacarbonylchromium) is a chromium(0) organometallic compound with the formula Cr(CO)6. It is homoleptic complex, which means that all the ligands are identical. It is a white, air-stable solid with a high vapor pressure. See more Like many metal carbonyls, Cr(CO)6 is generally prepared by "reductive carbonylation", which involves reduction of a metal halide with under an atmosphere of carbon monoxide. As described in a 2024 survey of … See more In chromium hexacarbonyl, the oxidation state for chromium is assigned as zero, because Cr-C bonding electrons come from the C atom and are still assigned to C in the hypothetical ionic bond which determines the oxidation states. The formula conforms … See more • Auteur., Job, André (1870-1928). (1927). Le chrome carbonyle et sa préparation par les organomagnésiens. impr. P. Dupont. OCLC 494793545. • Hieber, W.; Mühlbauer, F.
