摘要：

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 [Re-2(L)(CO)(6)Br-2], the Ag(I) double-stranded complexes of formula [Ag-2(L)(2)](ClO4)(2) and the Cu(II) triple-stranded complex of formula [Cu-2(L)(3)](ClO4)(4). Each type of them has been characterized using CD spectroscopy and if possible H-1 NMR spectroscopy. Three single crystal structures, one from each type, have been determined. (C) 2014 Elsevier Ltd.
