    Description / Table of Contents: Zusammenfassung Die Bildungskonstanten der ternären Komplexe von Cu(II), Zn(II) und Cd(II) mit Glycin (Gly),DL-Alanin (Ala) oderDL-Leucin (Leu) als Primärliganden und 2-(o-Hydroxyphenylazo)-2-cyanomethyl-benzimidazol (ABI) bzw. 5-(o-Hydroxyphenylazo)-barbitursäure (ABA) als Sekundärliganden wurden wurden ebenso wie jene binärer Systeme potentiometrisch in 40% (v/v) Ethanol bestimmt. Die Stabilität der ternären Komplexe wird mit jener der binären verglichen. Die Konzentration der verschiedenen Spezies in Lösung sowie ihre IR- und1H-HMR-Spektren wurden gemessen.
    Notes: Summary The overall formation constants of ternary complexes of Cu(II), Zn(II), and Cd(II) with glycine (Gly),DL-alanine (Ala), orDL-leucine (Leu) as primary and 2-(o-hydroxyphenylazo)-2-cyanomethyl benzimidazole (ABI) and 5-(o-hydroxyphenylazo) barbituric acid (ABA) as secondary ligands as well as those of the binary systems have been investigated potentiometrically in 40% (v/v) EtOH. The stability of the ternary complexes is compared quantitatively with that of the corresponding binary complexes. The concentration distribution of the species formed in solution was evaluated; they were characterized by means of IR and1H NMR spectroscopy.
