Özet

The syntheses, pK(a) and spectrospcopic characterization of [Fe(CN)(5)(H2O)](-3) and [Ru(CN)(5)(H2O)](-3) complexes of alanine(Ala), glycine(Gly), valine(Val), lysine(lys), arginine(Arg) and cysteine(Cys) complexes were investigated in aqueous solution. The spectra of the complexes containing amino acid ligands were similar to that of [Fe(CN)(5)(NH3)](-3). The pK(a) values of the complexes were measured by spectrophotometric titration at 22 degrees C and mu = 0.100 M(NaClO4).
