chromium hexacarbonyl white crystal. Stable in air, but volatile. Insoluble in water, methanol, ethanol, slightly soluble in iodoform, carbon tetrachloride, slightly soluble in tetrahydrofuran. It does not interact with hydrochloric acid, is slowly eroded by sulfuric acid, and is easily decomposed by nitric acid. When interacting with alkenes, alkynes, aromatics, phosphines, amines, etc., the carbonyl group is replaced to form a series of derivatives.
Chromium hexacarbonyl is a coordination compound. It is a solid at room temperature and has a high vapor pressure. It is easy to sublimate. The valence of the chromium atom in chromium hexacarbonyl is zero. It is a homogeneous compound. All carbonyl groups are equivalent. Its structure is octahedral, the bond lengths of Cr-C and C- O are 1.91 and 1.14 Å respectively. Chromium hexacarbonyl is used as a catalyst for olefin polymerization and isomerization, a gasoline additive, and a raw material for the preparation of chromium monoxide.
