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.

Current precious-metal-containing anticancer agents are mostly chelated with N-containing ligands and function by interacting with DNA. In the present study, Pd(acac)2, a Pd(II) complex containing four O-donor ligands, has been evaluated as an active anticancer agent. Pd(acac)2 showed no interaction

Nearly monodisperse lanthanide-doped magnetite nanoparticles were obtained by thermally decomposing a mixture of Fe(acac)(3) and Ln(acac)(3) (acac = acetylacetonate; Ln = Sm, Eu, Gd) in the presence of passivating surfactants. Magnetic studies revealed room-temperature ferromagnetic behaviors of these doped nanoparticles
