Chromium(II) acetate hydrate, also known as chromous acetate, is the coordination compound with the formula Cr 2 (CH 3 CO 2) 4 (H 2 O) 2. This formula is commonly abbreviated Cr 2 (OAc) 4 (H 2 O) 2 . This red-coloured compound features a quadruple bond .
The same structure is shared with basic iron acetate and basic manganese acetate. [2] [3] Little evidence exists for a simple chromium(III) acetate, i.e. lacking the oxo ligand. [4] Chromium(III) acetate is a blue/grey-green powder, which is soluble in water. It is still [3] prepared according to the original procedure from 1909. [5]
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+
The structure of chromocene has been verified by X-ray crystallography.The average Cr–C bond length is 215.1(13) pm. [6] Each molecule contains an atom of chromium bound between two planar systems of five carbon atoms known as cyclopentadienyl (Cp) rings in a sandwich arrangement, which is the reason its formula is often abbreviated as Cp 2 Cr.
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.

A commonly encountered acetate in the home is sodium acetate, a white solid that can be prepared by combining vinegar and sodium bicarbonate ("bicarbonate of soda"): CH 3 COOH + NaHCO 3 → CH 3 COO − Na + + H 2 O + CO 2. Transition metals can be complexed by acetate. Examples of acetate complexes include chromium(II) acetate and basic zinc ...
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]
Ball-and-stick model of chromium(II) chloride tetrahydrate. The hydrated derivative, CrCl 2 (H 2 O) 4 , forms monoclinic crystals with the P2 1 /c space group. The molecular geometry is approximately octahedral consisting of four short Cr—O bonds (2.078 Å) arranged in a square planar configuration and two longer Cr—Cl bonds (2.758 Å) in a ...
