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.
