copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to low toxicity and inexpensive, earth-abundant.

Two copper complexes based on nitronyl nitroxide with different halides: structures and magnetic properties was written by Wang, Xiang-Lan;Li, Yuan-Xia;Yang, Shuai-Liang;Zhang, Chen-Xi;Wang, Qing-Lun. And the article was included in Journal of Coordination Chemistry in 2017.Safety of copper(ii)hexafluor-2,4-pentanedionate This article mentions the following:

Complexes based on different halogen-substituted nitronyl nitroxide radicals and Cu(II), Cu3(hfac)6(NIT-Ph-F)2 (1) and Cu3(hfac)6(NIT-Ph-Cl)2 (2) (hfac = hexafluoroacetylacetonate; NIT-Ph-F = 2-(4′-fluorophenyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide; NIT-Ph-Cl = 2-(4′-chlorphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide), were synthesized and characterized structurally and magnetically. X-ray crystal structure analyses show that 1 and 2 have similar centrosym. five-spin structures consisting of three Cu(II) ions bridged by two nitroxide ligands. The Cu(II) is coordinated by six oxygens to form an octahedron, while the five coordination of the terminal Cu(II) ion is square pyramidal. Magnetic measurements reveal strong antiferromagnetic interactions between Cu(II) ions and radicals in 1 (J = -38.9 cm-1) and weak antiferromagnetic interactions between Cu(II) ions and radicals in 2 (J = -1.23 cm-1), which may be explained by the bond length of the Cu-Orad (2.468(2) Å) in , which is shorter than that (2.514(2) Å) in , and the dihedral angle (73.17(1)°) of the plane O7-O8-Cu(2)-O7A-O8A with the moiety O5-N1-C11-N2-O6 in 1 is smaller than (77.82(1)°) in 2. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Safety of copper(ii)hexafluor-2,4-pentanedionate).
