Abstract
The aqueous solution chemistry of the trimethyltin(IV) species and their complexes with amino acids has been studied by potentiometric technique. The results showed the formation of 1:1 complexes, and the corresponding stability constants were determined. The amino acid was bound to (CH
3)
3Sn(IV) as a monodentate ligand. The effect of the pK
a value of the respective ligand on the stability constant of its complex species with the organotin(IV) ion was elucidated. The concentration distribution of the complexes in solution was evaluated.
