It is a colorless liquid, classified as a 1,3- diketone. It exists in equilibrium with a tautomer CH3C (O)CH= (OH)CH3. These tautomers interconvert so rapidly under most conditions that they are treated as a single compound in most applications. [2]
Chromium(III) acetylacetonate is the coordination compound with the formula Cr(C5H7O2)3, sometimes designated as Cr(acac)3.
