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.
Application
Chromium(III) acetylacetonate may be used as an active site in the formation of redox systems for the fabrication of flow batteries. It may also be used as a precursor for chromium nitride based metallic coatings.
Analysis Note
Used to modify the surface properties of solid polyurethanes formed in its presence.
