Chromium acetate

Chromium acetate generally refers to a family of compounds containing chromium and acetate ligands, with the common form being chromium(III) acetate, also known as basic chromium acetate. Its characteristic cation is [Cr3O(O2CCH3)6(H2O)3]+, featuring three chromium(III) centers bridged by a triply bridging oxo ligand, six acetate ligands, and three aquo ligands. It appears as a blue or grey-green powder soluble in water.​

Chromium(II) acetate hydrate, another related compound, has the formula Cr2(CH3CO2)4(H2O)2. It is a red-colored compound with a notable quadruple bond between chromium atoms, and exists in dihydrate and anhydrous forms. This molecule has an octahedral geometry around each chromium and is diamagnetic due to the metal-metal bonding.​

Chromium acetates decompose on heating, ultimately forming chromium oxide, and are used in industrial applications such as catalysts and pigments. They are somewhat soluble in water and typical inorganic solvents.
