Binary and Ternary Interactions of Mercury(II )with Seven Pyrimidines and EthylenediaminetetraaceticAcid

Abstract

The introduction of an electronegative substituentat the C-5 position of a uracil ring leads to a decrease in thering’s complexation constants; the formation of mixedligand complexes of mercury(II ) takes place above pH 6and gives [Hg(edta)(thymine)]-type species, the mixedcoordination of which leads to enhanced stability.
