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.
Dufite inganda nyinshi zo mu rwego rwo hejuru hamwe nubufatanye bwimbitse, zishobora kuguha ibicuruzwa byiza kandi nibiciro byapiganwa. Turashobora kandi gutanga kugabanyirizwa kugura byinshi.Kandi turafatanya namasosiyete menshi yohereza ibicuruzwa byumwuga, birashobora gutanga ibicuruzwa neza kandi neza mumaboko yawe. Igihe cyo gutanga ni iminsi 3-20 nyuma yo kwemeza ko wishyuye.
