PURPLE CRYSTALLINE POWDER | [General Description]
Chromium(III) acetylacetonate is an acidopentamminechromium (111) salt, which is a crystalline material that can be prepared by treatment of precipitated hydrous chromium(III) oxide with acetylacetone. | [Flammability and Explosibility]
Notclassified | [reaction suitability]
core: chromium | [Purification Methods]
Purify it by dissolving 6g in hot *C6H6 (20mL) and adding 75mL of pet ether slowly. Cool to room temperature then chill on ice, filter off and dry in air to give 2.9g. It also crystallises from EtOH. It is soluble in heptane, *C6H6, toluene and pentane-2,4-dione at 20-40o. It forms a 1:2 complex with CHCl3.
