Chiral bipyridine ligands of different steric properties when reacted with CuCl 2 formed orange, yellow or green solids of new copper(II) complexes, [Cu(L)Cl 2 ] (L=L2–6), in good yield. Together with [Cu(L1)Cl 2 ], these complexes were characterized in solution by UV–Vis spectroscopy and cyclic voltammetry. The complexes give d–d transitions between 860 and 970nm, and exhibit...
Three new optically pure C 1 -terpyridine ligands (L1–3) were prepared and the copper(II) complexes, of formula [Cu(L)Cl 2 ], the rhodium(III) complexes, of formula [Rh(L)Cl 3 ], and the ruthenium(II) complexes, of formula cis- or trans-[Ru(L)(X)Cl 2 ] (X=DMSO or CO), were synthesized. Structures of a chiral C 1 -ligand, a copper complex, a rhodium complex and...
