Terminal fluoride ligands generate strong magnetic anisotropy in air-stable chiral dysprosium enantiomers supported by a bulky equatorial macrocycle, exhibiting a typical zero-field single-molecule magnet behaviour. [ABSTRACT FROM AUTHOR]

One-dimensional zig-zag chain and two-dimensional network dysprosium(III) single-molecule toroics with anisotropy barriers of about 5 and 31 cm−1 under a zero dc field are reported. These are the first one- and two- dimensional homometallic single-molecule toroics reported to date. Furthermore, the two complexes also display white-light emission under UV-light irradiation.

Two dysprosium complexes bearing unsupported Dy–Ge/Sn metal–metal bonds are reported here, wherein the Dy–Ge and Dy–Sn bonds both contain relatively large covalency. The complexes exhibit slow relaxation of magnetization at zero field with energy barriers of 485 and 620 K, respectively, and the blocking temperature of 6 K. [ABSTRACT FROM AUTHOR]

The first triradical bridged binuclear penta-spin single-molecule magnet, [Dy2(hfac)6(BTR)], based on a nitronyl nitroxide triradical was synthesized and characterized. Theoretical calculations revealed Dy-radical antiferromagnetic coupling and radical–radical ferromagnetic coupling. The SMM behavior is found to originate from the exchange states, rather than the isolated Dy3+ center. [ABSTRACT FROM AUTHOR]

Toroidal arrangements of magnetic moments are realized in heterometallic Ln6Cu6 (Ln = Tb and Dy) macrocycles thanks to the magnetic coupling between lanthanide and 3d metal ions. [ABSTRACT FROM AUTHOR]
