Abstract

The polydentate tripodal Schiff base ligand H3L has been prepared by treating a methanolic solution of tris(aminoethyl)amine and 5-bromosalicylaldehyde. This ligand, and its complexes with group-13 metal ions (Ga-III, In-III, and Tl-III) have been characterized by elemental analysis, NMR spectroscopy, FAB(+)-MS, and X-ray diffraction analysis. The ligand, not preorganizedin the solid state, acts as a hexadentate N3O3 ligand in all cases to formoctahedral structures, the apical nitrogen not being involved in the chelation even for the [Tl(L)] complex. NMR studies reveal that the intact and rigid structures of the complexes are maintained in solution. For the [Tl(L)] complex, long-range thallium isotope effect on the chemical shift (delta (H) and delta (C)) and on the coupling constants (J(Tl-H) and J(Tl-C)) has been observed, confirming a strong and stable bond between Tl-III and H3L.
