Abstract
Three potentially quinquedentate ligands, 1,11-diamino-6-oxa-3,9-dithiaundecane (LO), 1,6,11-triaza-3,9-dithiaundecane (LN), 1,11-diamino-3,6,9-trithiaundecane (LS) and their quadridentate analogue 1,11-diamine-3,9-dithiaundecane (LC) were prepared. Their copper(II) complexes of composition CuL(ClO

2 was the main product. ESR spectroscopy showed that the copper(II) complex with LO has rhombic symmetry, whereas the complexes with LN and LS are tetragonal, and the dimeric LC complex exhibits a weak Cu(II)-Cu(II) interaction. The cyclic voltammograms of the complexes with the quinquedentate ligands show a negative potential shift in comparison with the complex with the tetradentate ligand LC. Under CO, the E
