Structural and Magnetic Properties of 2p-3d-4f Hetero-Tri-Spin Chains Comprising [{Cu(hfac)2-Radical}2] Dimers and Ln(hfac)3 (hfac = hexafluoroacetylacetonate) was written by Zhu, Mei;Yang, Meng;Wang, Juanjuan;Li, Hongdao;Li, Licun. And the article was included in Chemistry – An Asian Journal in 2016.SDS of cas: 14781-45-4 This article mentions the following:
A new family of 2p-3d-4f hetero-tri-spin complexes [Ln(hfac)3{Cu(hfac)2(NIT-3 PyPh)}2] (Ln = Gd (1), Tb (2), Dy (3), Ho (4); NIT-3 PyPh = 2-[4-(3-pyridinylmethoxy)phenyl]-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide; hfac = hexafluoroacetylacetonate) were synthesized. The four complexes possess a 1-dimensional chain structure in which two radical ligands join two Cu(hfac)2 mols. to form a [{Cu(hfac)2-rad}2] dimer cycle and the dimer rings are linked by Ln(hfac)3 units. Magnetic studies show that ferromagnetic exchange couplings exist between the coordinated NO groups of radical ligands and metal ions. Field-induced slow relaxation of the magnetization was observed in the Tb and Dy compounds In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4SDS of cas: 14781-45-4).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. Transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents belong to the most important cross-coupling reaction in organic synthesis. Copper nanoparticles can catalyze the Ullmann coupling reaction in a wide range of applications.SDS of cas: 14781-45-4
