Role of the Templating Heteroatom on Both Structural and Magnetic Properties of POM‐Based SIM Lanthanoid Complexes

The plasticity of the coordination chemistry Lanthanoid ions (LnIII) has allow design novel compounds with slow relaxation magnetization since first Single Ion Magnet (SIMs) was reported by Ishikawa, who used phthalocyaninate ligand to make a “sandwich type” complex. allowed possibility different types molecular complexes SIMs behaviour based on organic ligands. There is also inorganic ligands, using lacunary polyoxometalates (LPOM) like, [XW11O39]n−. combination both ligands can produce hybrid inorganic-organic LnIII SIM behaviour. This an attractive approach these materials could benefit from ease functionalization robustness moieties. are reports that mononuclear DyIII complex improve dynamics when it compared analogues. Thus, in this review we present study and comparison improvement cause geometry metal centres fully (mononuclear dinuclear) lanthanoid (for DyIII, ErIII YbIII). Moreover, will discuss which changes modify magnetic properties Complexes.
