There has been a renaissance in the interdisciplinary field of Molecular Magnetism since ~2000, due to discovery impressive properties and potential applications d- f-metal Single-Molecule Magnets (SMMs) Single-Ion (SIMs) or Monometallic Magnets. One consequences this an explosive growth synthetic molecular inorganic organometallic chemistry. In SMM SIM chemistry, organic ligands play decisive role, sometimes equally important that magnetic metal ion(s). bridging propagate strong...
Three field induced SMMs built from quasi-isotropic cations like CuII and MnII have been characterized, showing that relatively large clusters with quasi-negligible D different ground spin states, S = 3/2, 2 or 4, can also exhibit field-induced slow relaxation of magnetization.
A series of tetranuclear Cu2IILn2III (LnIII from LaIII to YbIII), double-stranded metallohelicates have been synthesized using a bis-bidentate flexible ligand obtained by condensing o-vanillin with 4,4′-oxydianiline. The complexes exhibit variety LnIII environments and decreasing coordination number along the several nitrato modes proved structural determination (1La), SmIII (4Sm), GdIII (5Gd), ErIII (9Er), YbIII (10Yb) derivatives. other members family (2Ce, 3Pr, 6Tb, 7Dy, 8Ho)...
