A new mononuclear terbium and copper cocrystalline nitronyl nitroxide complex: synthesis, structure and magnetic properties was written by Shi, Jian Yun;Ma, Zhi Long;Tian, Li. And the article was included in Journal of Molecular Structure in 2021.Application of 14781-45-4 This article mentions the following:
One 2p-3d-4f multispin complex [Cu(hfac)(4-Me-3-NITtrz)2][Tb(hfac)4]·H2O (1) was obtained based on a functionalized nitronyl nitroxide radical 4-Me-3-Nit-trz (in which, 4-Me-3-Nit-trz = 2-[3-(4-methyl-l,2,4-triazolyl)]-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, hfac = hexafluoroacetylacetone). Complex 1 crystallizes in tetragonal system, I4 space group. The central CuII ion is six-coordinated in tensile octahedron configuration finished by two bidentate radical ligands and one bidentate hfac anion, while TbIII ion exhibited as distorted triangular dodecahedron geometry (D2d) finished by eight oxygen atoms from four bischelate hfac anions. Magnetic studies show that Cu(II) ion and the NO group are antiferromagnetically coupled with coupling constants of JCu-rad = 1.76-1.99 cm-1, and strong antiferromagnetic exchange interactions between the two intramol. radicals with Jrad-rad = -12.88∼-10.42 cm-1 exist in 1. In addition, a.c. magnetic susceptibilities were further measured. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Application of 14781-45-4).
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 the earth-abundant, low toxicity and inexpensive. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Application of 14781-45-4
