文摘

It is the first time these ternary systems are studied. In the Cu(II)-2-(benzo[d]oxazol-2-yl)nicotinic acid (HL) system six complexes were observed. The Cu(II)-L− system has a similar stability constants as the Cu(II)-2,2′-Bipyridine system. In the complex [Cu(L)(HB)]+ probably the amino acids are monocoordinated to the Cu(II) trough the carboxylate group. In the rest of the ternary complexes both ligands are acting as bidentate ligand.
