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+
A tetrahedral coordination of chromium(III) has been reported for the Cr-centered Keggin anion [α-CrW 12 O 40] 5–. [11] Chromium(III) hydroxide (Cr(OH) 3) is amphoteric, dissolving in acidic solutions to form [Cr(H 2 O) 6] 3+, and in basic solutions to form [Cr(OH) 6] 3−. It is dehydrated by heating to form the green chromium(III) oxide ...
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.
Molar mass: 151.9904 g/mol Appearance light to dark green, fine crystals ... Chromium(III) oxide (or chromia) is an inorganic compound with the formula Cr 2 O 3.
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 ...
The molecular formula C 18 H 12 CrN 3 O 6 (molar mass: 418.300 g/mol) may refer to: ... Chromium(III) picolinate This page was last edited on 24 August 2019, at 03:22 ...
Chromium(III) acetylacetonate is the coordination compound with the formula Cr(C 5 H 7 O 2) 3, sometimes designated as Cr(acac) 3. This purplish coordination complex is used in NMR spectroscopy as a relaxation agent because of its solubility in nonpolar organic solvents and its paramagnetism .
Hydrated chromium(III) sulfate, Cr 2 (SO 4) 3 ·18H 2 O, (CAS #13520-66-6) is a violet solid that readily dissolves in water to give the metal aquo complex, [Cr(H 2 O) 6] 3+. The formula of this compound can be written more descriptively as [Cr(H 2 O) 6 ] 2 (SO 4 ) 3 ·6H 2 O. Six of the eighteen water molecules in this formula unit are water ...
