Slow Magnetic Relaxation Behavior in Rare Ln-Cu-Ln Linear Trinuclear Complexes was written by Zhang, Junqing;Li, Cun;Wang, Juanjuan;Zhu, Mei;Li, Licun. And the article was included in European Journal of Inorganic Chemistry in 2016.Category: copper-catalyst This article mentions the following:
Three novel heterotrinuclear complexes {[Ln(hfac)3]2CuL2} [LnIII = Gd (1), Tb (2), and Dy (3); HL = 4-methoxysalicylaldehyde, hfac = hexafluoroacetylacetonate] were synthesized and characterized by x-ray crystallog. as well as by a study of their magnetic properties. In these compounds, CuII and LnIII ions are bridged by two phenolato and aldehyde O atoms from two 4-methoxysalicylaldehyde ligands and one O atom from one hfac ligand, resulting in a linear trinuclear core of Ln-Cu-Ln with one central CuII ion and two terminal LnIII ions. Also, the linear trinuclear units generate a pseudo-one-dimensional chain through π-π interactions. Direct-current magnetic susceptibility studies show that there is a ferromagnetic interaction between CuII and GdIII ions. Tb and Dy complexes exhibit frequency-dependent out-of-phase signals, indicating slow magnetic relaxation behavior. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Category: copper-catalyst).
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. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. Category: copper-catalyst
