摘要：

The formation constants for 1:1 molecular complex formation between water-soluble cobalt(II) tetradentate Schiff base complex, disodium[{bis(4-methoxy-5-sulfo-salicylaldehyde)-4,5-dimethyl-o-phenylenediiminato}cobalt(II)], Na(2)[Co(SO(3)-4-meosal-4,5-dmophen)], and nucleotides, adenosine-5 '-triphosphate (ATP) and cytidine-5 '-triphosphate (CTP), in mixed solvent systems of ethanol and water with different volume fractions of ethanol and water have been determined spectrophotometrically at constant ionic strength (I=0.2 mol dm(-3) NaClO(4)) and temperature 278 K. Trends in the values of formation constants according to the volume fractions of ethanol and water in ethanol and water mixed solvent systems, suggest that the trend of molecular complex formation increases with increasing the volume fraction of ethanol in mixed solvent systems.
