Abstract
Reaction of Cd(II) ion with hypoxanthine (H2 Y) and with 6-mercaptopurine (H2 MP) in dioxane-water (50%) leads to the formation of CdY·2H2O and Cd(HMP)2·2H2O, respectively. In methanolic medium Cd(II) and H2 MP give Cd(MP)·H2O. These compounds have been characterized by chemical analysis, IR spectra and thermogravimetric analysis. The stability constant of CdY complex at 25±0.1 °C and 1M ionic strength with NaClO4 in dioxane-water medium is log β=10.25±0.05.
Zusammenfassung
Die Umsetzung von Cd(II)-Ionen mit Hypoxanthin (H2 Y) und 6-Mercaptopurin (H2 MP) in Dioxan-Wasser (50%) ergibt die Verbindungen CdY·2H2O und Cd(HMP)2·2H2O. In Methanol entsteht aus Cd(II) und H2 MP CdMP·H2O. Die Verbindungen wurden durch chemische Analysen, IR-Spektren und thermogravimetrische Analysen charakterisiert. Die Stabilitätskonstante der Verbindung CdY bei 25°C und bei einer Ionenstärke = 1 (NaClO4) in Dioxan-Wasser wurde zu lg β=10,25±0,05 bestimmt.
