摘要：

Spotting trends: Upon going from TbIII to YbIII centers in the complexes of the DOTA4- ligand, a reorientation of the easy axis of magnetization from perpendicular to parallel to the Ln-O bond of the apical water molecule is experimentally observed and theoretically predicted (see picture; SMM = single-molecule magnet). Only ions with an odd number of electrons show slow relaxation of the magnetization. © 2013 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
