Abstract

The preparation and characterization of Ln(III) complexes (Ln=Sm, Yb) of tripodal heptadentate ligand trensal, tris[2-(salicylideneamino)ethyl]amine (H₃L¹) have been studied. The molecular structures of [LnL¹] were determined by X-ray structural analysis; these are heptadentate complexes in which the metal ions are coordinated by the three oxygen atoms and the four nitrogen atoms. [LnL¹] is a novel example because the coordination number is seven in the wide range of the series of [LnL¹] (Ln=Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu). This has made it possible to compare the bond lengths for the lanthanide and yttrium complexes under the same coordination number.
