| Abstract: | The stability constants of the complexes MeHgL]?(H2L = 2-mercaptopyridine-3-carboxylic acid, 2-mercaptopyridine-4-carboxylic acid, 2-mercaptopyridine-5-carboxylic acid and 2-mercaptopyridine-6-carboxylic acid) have been obtained by differential pulse polarography. The values of log β1 are in the range 14.14–14.96 at 20°C and ionic strength 0.1 mol dm?3. The complexes MeHgHL have been isolated and characterized by chemical analysis and mass and IR spectrometry. |
