A disc-like heptanuclear Co(II)-cluster, [Co7(bzp)6(N3)9(CH3O)3].2ClO4.2H2O (1) (bzp = 2-benzoyl pyridine), mixed-bridged by 3/4 azides (mu1,1 and mu1,1,1) and 1/4 mu1,1,1-methanol, shows slow relaxation at static zero and non-zero fields below 6 K, towards single molecule magnet behavior.
متن کاملHeterotrimetallic 3d-4d-4f decanuclear metal-capped square showing single-molecule magnet behavior.
The synthesis, the structural characterization and the magnetic properties of a heterotrimetallic decanuclear square, [(Mo(CN)(8))(2)(CuLTb)(4))](4+), noted MoCuTb, are described. This supramolecular compound, viewed as the first example of a metal-capped square, behaves as a single molecule magnet with a magnetic anisotropic barrier energy of U(eff) = 13.40 cm(-1) (19.25 K).

The syntheses, structures, and characterization of four 3d-4f butterfly clusters are described. With different polyhydroxy Schiff-base ligands 2-(((2-hydroxy-3-methoxyphenyl)methylene)amino)-2-(hydroxymethyl)-1,3-propanediol (H4L1) and 2-(2,3-dihydroxpropyliminomethyl)-6-methoxyphenol (H3L2), three heterotetranuclear NiLn complexes (NiDy-L1 (1), NiTb-L2 (2), NiDy-L2 (3)) and one heterohexanucle...
متن کاملHeterometallic 3d-4f single-molecule magnets.
The promising potential applications, such as information processing and storage or molecular spintronics, of single-molecule magnets (SMMs) have spurred on the research of new, better SMMs. In this context, lanthanide ions have been seen as ideal candidates for new heterometallic transition metal-lanthanide SMMs. This perspective reviews 3d-4f SMMs up to 2014 and highlights the most significan...
متن کاملMultiple Magnetization Reversal Channels Observed in a 3d-4f Single Molecule Magnet
The present study discusses the magnetic dynamics of a previously reported cyanide bridged 3d-4f dinuclear DyIIICoIII complex. Following the axial anisotropy suggested by previous Electron Paramagnetic Resonance spectroscopy (EPR) analysis, the complex turned out to show slow relaxation of the magnetization at cryogenic temperature, and this was studied in different temperature and field regime...
