Description
Summary:The first family of hybrid mononuclear organic-inorganic lanthanoid complexes is reported, based on [PW 11 O 39 ] 7− and 1,10-phenanthroline ligands. This hybrid approach causes a dramatic improvement of the relaxation time (×1000) with a decrease of the optimal field while maintaining the U eff of the inorganic analogues. The plasticity of the coordination chemistry of lanthanoid ions has allowed the design and synthesis for the first time of a family of mononuclear hybrid organic-inorganic lanthanoid complexes with slow relaxation of the magnetization.
