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 .
Chromium(II) acetate, Cr 2 (μ-O 2 CCH 3) 4 (H 2 O) 2, was the first chemical compound containing a quadruple bond to be synthesized. It was described in 1844 by E. Peligot, although its distinctive bonding was not recognized for more than a century.
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+
Well studied examples include the dimetal tetraacetates (M 2 (OAc) 4) including rhodium(II) acetate, copper(II) acetate, molybdenum(II) acetate, and chromium(II) acetate. Platinum diacetate and palladium diacetate feature Pt 4 and Pd 3 cores, further illustrating the tendency of acetate ligands to stabilize multimetallic structures.
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]

In 1844 he synthesized chromium(II) acetate, [6] [7] which was much later recognized (by F. Albert Cotton in 1964) to be the first chemical compound which contains a quadruple bond. [ 8 ] See also
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]
