| Abstract: | Stability constants of the 1 : 1 and 1 : 2 metal-thiamine (vitamin B1) complexes and 1: 1 : 1 metal-thiamine-thymine/uracil mixed ligand complexes have been determined in aqueous medium by potentiometric method at 35° ± 0.1°C and μ = 0.10 M (KNO3). The log K values for 1:2 metal-thiamine systems are positive whereas values for 1: 1 : 1 metal-thiamine-thymine or -uracil systems are negative. So the log K values reveal that mixed ligand complexes are less stable than the binary (1:1) complexes. |
