The anhydrous form of chromium(II) acetate, and also related chromium(II) carboxylates, can be prepared from chromocene: 4 RCO 2 H + 2 Cr(C 5 H 5) 2 → Cr 2 (O 2 CR) 4 + 4 C 5 H 6. This method provides anhydrous derivatives in a straightforward manner. [8] Because it is so easily prepared, Cr 2 (OAc) 4 (H 2 O) 2 is a
Chromium acetate hydroxide is the coordination complex with the formula [Cr 2 (OH) 3 (OAc) 3] 4. A dark violet solid, it crystallizes as the triacontatetrahydrate (34 molecules of water of crystallization). It is water soluble. [1]
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(VI) by cytochrome c7. [9] The Cr 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 ...
For simple carboxylates, the acetate complexes are illustrative. Most transition metal acetates are mixed ligand complexes. One common example is hydrated nickel acetate, Ni(O 2 CCH 3) 2 (H 2 O) 4, which features intramolecular hydrogen-bonding between the uncoordinated oxygens and the protons of aquo ligands. Stoichiometrically simple ...
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
Chromium(III) hydroxide is a gelatinous green inorganic compound with the chemical formula Cr(OH) 3. It is a polymer with an undefined structure and low solubility. It is amphoteric, dissolving in both strong alkalis and strong acids. [2] In alkali: Cr(OH) 3 + OH − → CrO − 2 + 2 H 2 O In acid: Cr(OH) 3 (OH 2) 3 + 3 H + → Cr(OH 2) 6 3+
Chromates react with hydrogen peroxide, giving products in which peroxide, O 2− 2, replaces one or more oxygen atoms.In acid solution the unstable blue peroxo complex Chromium(VI) oxide peroxide, CrO(O 2) 2, is formed; it is an uncharged covalent molecule, which may be extracted into ether.
