The divalent metallocene complexes Ln(CpiPr5)2 (Ln = Tb, Dy) were synthesized through the KC8 reduction of Ln(CpiPr5)2I intermediates and represent the first examples of neutral, linear metallocenes for these elements. X-ray diffraction analysis, DFT calculations, and magnetic susceptibility measurements indicate a 4fn5d1 electron configuration with strong s/d mixing that supports the linear coordination geometry. A comparison of the magnetic relaxation behavior of the two divalent metallocenes…

Carbonyl Back-Bonding Influencing the Rate of Quantum Tunnelling in a Dysprosium Metallocene Single-Molecule Magnet.
The finding that a classical organo-transition-metal bonding scenario can be used as an indirect way of tuning the rate of quantum tunnelling potentially provides an alternative chemical strategy for utilizing the fast magnetic relaxation properties of SMMs.

Trends in trigonal prismatic Ln-[1]ferrocenophane complexes and discovery of a Ho3+ single-molecule magnet†
It is found that larger average Fc2− twist angles result in faster magnetic relaxation times at a given temperature, and the magneto-structural relationship of the trigonal prismatic Ho-[1]ferrocenophane motif was further investigated.
Successive syntheses and magnetic properties of homodinuclear lanthanide macrocyclic complexes.
Single-crystal X-ray analyses show that the central Ln3+ ion adopts a distorted square antiprism conformation with D4d local symmetry, and magnetic studies reveal ferromagnetic interaction between Dy3+ and Tb3+ centres and zero-field slow relaxation of magnetization for Dy complexes 1 and 4.

A new mononuclear Dy(iii) complex, with the formula [Dy(Hcpt)3]·2H2O (1), has been successfully prepared via self-assembly between Dy(iii) ions and 2-cyano-N′-(1-(pyridin-2-yl)amido)acetyl (Hcpt)

Analysis on the dilution sample (1@Y) and ab initio calculation unveil that the thermally assisted slow relaxation is mostly caused by the single-ion magnetism of DyIII itself.

The magnetization relaxation pathways are discussed and a satisfactory fit of the temperature and field dependencies of the relaxation time τ was achieved considering a model that employs Raman, direct, and Orbach relaxation mechanisms.
Remarkable Energy Barrier for Magnetization Reversal in 3D and 2D Dysprosium-chloranilate Based Coordination Polymers.
The temperature and field dependence of relaxation time indicate the presence of multiple relaxation like direct, QTM, Raman, and Orbach processes in both the CPs, and the values for CP 1 and CP 2 represent remarkable energy barrier of magnetization reversal in any metal-chloranilate based 3D (CP 1) and 2D coordination polymers [Anchor].
