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]

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 .
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 ).
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.
Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist. [3] [4]
