Summary: Pd(dmen)Cl2 complex, was synthesized and characterized, where dmen= N,N-dimethylethylenediamine. Stoichiometry and stability constants of the complexes formed between [Pd(dmen)(H2O)2]2+ and various biologically relevant ligands as amino acids, peptides and dicarboxylic acids are investigated at 25ºC and at constant 0.1 M ionic strength. Amino acids and dicarboxylic acids form 1:1 complexes. Peptides form two complex species Pd(dmen)L and Pd(dmen)(LH-1) The concentration distribution diagrams of the various species formed are evaluated. |
