Abstract: The interaction of trace metal ions, viz. MnII, CoII, NiII, CuII, ZnII and CdII with adenine (A) as primary ligand and 5-halouracils, viz. 5-bromouracil (5BrU) and 5-iodouracil (5IU) as secondary ligands (L) has been studied at 25 ± 0.1 °C and at constant ionic strength (μ = 0.1 M NaNO3), in an aqueous medium using Bjerrum-Calvin's pH-titration technique as adopted by Irving and Rossotti for binary (ML), and by Chidambaram and Bhattacharya for ternary (MAL) systems respectively. The experimental pH-titration data were analyzed with the aid of the BEST computer program in order to evaluate formation constants of various intermediate complex species formed in binary and ternary systems involving nucleobases (viz. A, 5BrU and 5IU). The relative stability of each ternary complex was compared with that of the corresponding binary complexes in terms of Δlog K values.
