Abstract

With a series of chiral pyridine-based tetradentate pyridyl-thiazole ligands L, three types of binuclear helical metal complexes were synthesized. They were the Re(I) single-stranded complexes of formula [Re2(L)(CO)6Br2], the Ag(I) double-stranded complexes of formula [Ag2(L)2](ClO4)2 and the Cu(II) triple-stranded complex of formula [Cu2(L)3](ClO4)4. Each type of them has been characterized using CD spectroscopy and if possible 1H NMR spectroscopy. Three single crystal structures, one from each type, have been determined.
