    Description / Table of Contents: Durch potentiometrische Titrationen in konzentrierten KCN-Lösungen wurden außer den in der Literatur bekannten Komplexen die Anionen [Hg(CN)5]3- und [Hg(CN)6]4- ermittelt. Instabilitätskonstanten, Standardpotentiale und freie Energien wurden berechnet. Sobald über die Formel Hg(CN)2 hinaus ein kleiner Überschuß von HgCl2-Lösung zugegeben wurde, bildete sich Hg2Cl2 auf der Elektrode.
    Notes: By potentiometric titrations, in addition to the complexes known in literature, the anions [Hg(CN)5]3- and [Hg(CN)6]4- have been evaluated in concentrated solutions of KCN. Instability constants together with standard potentials and free energies were calculated. - After the complete formation of Hg(CN)2 and addition of slight excess of HgCl2 the electrode became incapacitated on account of the formation of Hg2Cl2.
