Zusammenfassung

2,5-Dibenzoyl-3,4-dihydroxyselenophen bildet im pH-Bereich zwischen 7,0 und 9,5 mit Blei, Kobalt, Kupfer, Nickel und Zink Komplexe der Zusammensetzung 1∶1, die nach der Methode der stetigen Veränderung und nach der Methode der molaren Verhältnisse bestimmt wurde. Die Logarithmen der Stabilitätskonstanten dieser Komplexe wurden nach zwei verschiedenen Methoden ermittelt und betragen 5,4 bis 6,9.

Summary

2,5-Dibenzoyl-3,4-dihydroxyselenophen, in the pH region between 7.0 and 9.5, reacts with lead, cobalt, copper, nickel and zinc to yield complexes having the composition 1∶1, which were determined by the method of continuous variation and by the method of molar ratios. The logarithms of the stability constants of these complexes were determined by two different methods; they were found to be 5.4 to 6.9.
