Abstract

The thermal behaviour of the entitled nickel(II) and copper(II) complexes of ¯4-acetylamino-2-hydroxy-5-methyl azobenzene has been studied by means of differential thermal analysis (DTA), thermogravimetry (TG), X-ray powder diffraction, IR and electrical conductivity. A light has been thrown on the nature of interaction of the solvents of crystallization with the host complex. Some of the kinetic parameters are calculated and discussed.

Zusammenfassung

Mittels DTA, TG, Röntgendiffraktionsuntersuchungen, IR und elektrischen Leitfähigkeitsmessungen wurde das thermische Verhalten der Titelverbindungen untersucht. Bei diesen ¯4-Acetylamino-2-hydroxy-5-methyl-azobenzolkomplexen von Nickel(II) und Kupfer(II) wurde auch die Natur der Wechselwirkung des Lösungsmittels der Kristallisierung mit der Komplexverbindung ergründet. Einige der kinetischen Parameter wurden berechnet und diskutiert.
