Synthesis of novel lanthanide complexes with quinone-containing ligands and their redox controlled magnetic interaction
New lanthanide-quinone and semiquinone complexes with the formula [Ln(L)(2)(OTf)(3)] and [Ln(L')(2)(OTf)] (Ln = La, Gd, and Yb; OTf = CF3SO3_; L = aminoquinone ligand; L= aminosemiquinone ligand), respectively, were synthesized, and the magnetic interaction between f-electrons and organic radicals was revealed.
