Six pentanuclear LnIII clusters have been isolated based on thiacalix[4]arene ligand for the first time. Two Dy5 clusters feature distinct slow magnetic relaxation, which is affected presumably by the ligand, field molecular symmetry and coordination geometries of lanthanide ions.

Frequency Relaxation

A series of mononuclear Co(II) complexes showing slow magnetic relaxation is assessed from the point of view of relaxation mechanisms. In certain cases, the reciprocating thermal behavior is detected: On cooling, the slow relaxation time is prolonged until a certain limit and then, unexpectedly, is accelerated. The low-temperature magnetic data can be successfully fitted by assuming Raman and/or phonon bottleneck mechanisms of the slow magnetic relaxation for the high-frequency relaxation channel. An additional term with the negative temperature exponent is capable of reproducing the whole experimental dataset.
