Solution equilibria of the system palladium (II)‐diethylenetriamine ( dien ) and peptides have been studied. The p H‐metric titration of the reaction mixture containing equimolar solutions of palladium (II), dien and peptide have shown the formation of 1:1:1 mixed ligand complex. The pK e of the peptides studied and formation constants of the resulting complexes have been determined at 25° C . The mode of chelation has been deduced from the conductivity measurements.
