    Description / Table of Contents: Chelates of 8-Quinolinol Derivatives. IV. Properties, Adduct Formation, and Extraction of Nickel(II) Chelates with n-Alkyl-8-quinolinols Containing Long Chain SubstituentsThe nickel(II) chelates of 5- and 7-nonyl-, 5- and 7-decyl- and 5-chlor-7-decyl-8-quinolinol as well as adducts with water and ammonia were synthesized and characterized by spectra and magnetic moments. The existence of associated forms was concluded. To characterize the influence of substituents the stability and composition of pyridine adducts in solution were determined. Finally the extraction of nickel(II) was studied, and a comparison of extraction data with acid and coordination stability constants was made in the case of the isomeric nonyl-8-quinolinols.
    Notes: Es wurden die Nickelchelate sowie Aquo- und Amminaddukte von 5- und 7-Nonyl-, 5- und 7-Decyl- sowie 5-Chlor-7-decylchinolin-8-ol dargestellt und spektroskopisch wie magnetochemisch untersucht. Daraus ist auf das Vorliegen assoziierter Formen zu schließen. Der Charakterisierung des Substituenteneinflusses diente die Bestimmung von Stabilität und Zusammensetzung der Pyridinaddukte in Lösung. Schließlich wurde die Extraktion von Nickel untersucht und am Beispiel der isomeren Nonylchinolin-8-ole ein Vergleich der Extraktionsdaten mit Säure- und Komplexstabilitätskonstanten vorgenommen.
