Abstract
A trinuclear [Fe2Tb] (for Fe(II) and Tb(III)) cluster, with the formula of [Tb(HFac)3(Fe-NO-Butan)] (HFac = hexafluoroacetylacetonate; Fe-NO-Butan = bi(ferrocenylmethyl)-2,3-bi(N-oxide)-2,3-dimethylbutan) based on a nitrogen oxidation bidentate chelate ligand, has been successfully constructed and structurally characterized, which is composed of two diamagnetic ferrocenyl segments and a paramagnetic [Tb(HFac)3] unit. Magnetic investigation reveals that [Fe2Tb] compound exhibits field-induced slow magnetic relaxation behavior with effective barrier Δeff/kB ≈ 12.80 K, deriving from isolated anisotropic Tb3+ ion.
期刊介绍：
Russian Journal of Coordination Chemistry is a journal that publishes reviews, original papers, and short communications on all aspects of theoretical and experimental coordination chemistry. Modern coordination chemistry is an interdisciplinary science that makes a bridge between inorganic, organic, physical, analytical, and biological chemistry.
