A large number of chromium(III) compounds are known, such as chromium(III) nitrate, chromium(III) acetate, and chromium(III) oxide. [33] Chromium(III) can be obtained by dissolving elemental chromium in acids like hydrochloric acid or sulfuric acid, but it can also be formed through the reduction of chromium(VI) by cytochrome c7. [34] The Cr 3+

Anhydrous chromium(III) chloride (CrCl 3) A large number of chromium(III) compounds are known, such as chromium(III) nitrate, chromium(III) acetate, and chromium(III) oxide. [8] Chromium(III) can be obtained by dissolving elemental chromium in acids like hydrochloric acid or sulfuric acid, but it can also be formed through the reduction of ...
Chromium(III) acetylacetonate, Cr(acac) 3, is a typical octahedral complex containing three acac − ligands. Like most such compounds, it is highly soluble in nonpolar organic solvents. Like most such compounds, it is highly soluble in nonpolar organic solvents.
Chromium(III) acetate, commonly known as basic chromium acetate, [2] describes a family of salts where the cation has the formula [Cr 3 O(O 2 CCH 3) 6 (OH 2) 3] +. The trichromium cation is encountered with a variety of anions, such as chloride and nitrate. Data in the table above are for the chloride hexahydrate, [Cr 3 O(O 2 CCH 3) 6 (OH 2) 3 ...
Because of the very high melting point of chromium, chromium thermite casting is impractical. Heating with chlorine and carbon yields chromium(III) chloride and carbon monoxide: Cr 2 O 3 + 3 Cl 2 + 3 C → 2 CrCl 3 + 3 CO. Chromates can be formed by the oxidation of chromium(III) oxide and another oxide in a basic environment: 2 Cr 2 O 3 + 4 MO ...
The compound is prepared by the reaction of chromium(III) oxide with acetylacetone (Hacac): [3] Cr 2 O 3 + 6 Hacac → 2 Cr(acac) 3 + 3 H 2 O. The complex has idealized D 3 symmetry. The Cr-O distances are 1.93 Å. [4] The complex has been resolved into individual enantiomers by separation of its adduct with dibenzoyltartrate. [5]
Chromium(III) picolinate (also trivalent chromium) is a chemical compound with the formula Cr(C 5 H 4 N(CO 2)) 3, commonly abbreviated as CrPic 3. It is a bright-red coordination compound derived from chromium(III) and picolinic acid.
