Observation of slow magnetic relaxation in triple-stranded lanthanide helicates
Dalton Transactions, 2011Two dinuclear triple-stranded helicates [Ln(2)L(3)](3+) (Ln = Dy and Tb) obtained via self-assembly from the ligand HL (2,6-diformyl-4-methylphenol di(benzoylhydrazone)) and lanthanide perchlorate have been synthesized and characterized. The crystal structural analysis demonstrates that three ligand strands wrap around a pseudo-threefold axis defined ...

Instead of assembling complex clusters and/or expensive lanthanide-based systems as single ion magnets, we are focusing on mononuclear cobalt(II) systems among which the complex under study, [Co( pydca)( dmpy)]2·H2O (1), shows a field supported slow ...

Tridecanuclear and Docosanuclear Manganese Phosphonate Clusters with Slow Magnetic Relaxation
Inorganic Chemistry, 2007Two novel mixed-valent manganese phosphonate clusters [MnIIMnIII12O6(OH)6(O3PC6H11)10(py)6] (1) and [MnII4MnIII18O12(O3PC6H11)8(O2CCH3)22(H2O)6(py)2] (2) are reported in this paper. Complex 1 is the first carboxylate-free manganese phosphonate cluster.

Slow Magnetic Relaxation in a Trigonal Prismatic Uranium(III) Complex
Journal of the American Chemical Society, 2009Results of ac magnetic susceptibility measurements performed on the trigonal prismatic complex U(Ph(2)BPz(2))(3) demonstrate the presence of slow magnetic relaxation under zero applied dc field. Analysis of both the temperature and frequency dependence of the ac susceptibility indicate a temperature regime (T > approximately 3 K) where Arrhenius ...

Single Pyramid Magnets: Dy5 Pyramids with Slow Magnetic Relaxation to 40 K
Angewandte Chemie, 2011Single-molecule magnets: A square-pyramidal pentametallic dysprosium cluster (see picture) was synthesized and showed slow magnetic relaxation at temperatures as high as 40 K. The thermal energy barrier to relaxation of magnetization of this single-molecule magnet is 530 K and is the largest yet observed for any d- or f-block cluster compound ...
