Three
seven-coordinate lanthanide(III) sandwich-type mononuclear complexes
with π-conjugated TTF-Schiff base ligand H2L (L2– = 2,2′-((2-(4,5-bis(methylthio)-1,3-dithiol-2-ylidene)-1,3-benzodithiole-5,6-diyl)bis(nitrilomethylidyne)bis(4-chlorophenolate))
and the tripodal ligand LOEt– (LOEt– = [(η5-C5H5)Co(P(O)(OEt)2)3]−), [(LOEt)Ln(L)]·0.25H2O
(Ln3+ = Dy3+, 1; Tb3+, 2; Ho3+, 3), have been synthesized
and structurally characterized. All of the complexes are also characterized
by absorption spectra and electrochemical, spectroelectrochemical,
and magnetic studies. The Dy complex exhibits the field-induced slow
relaxation of magnetization with an energy barrier of 41.6 K, indicating
it shows single lanthanide-based SMM behavior. Introduction of the
redox-active TTF unit into the sandwich-type lanthanide(III) complexes
with interesting magnetic properties renders them promising for elaboration
of new hybrid inorganic–organic materials.
