Formation constants for the complexes of 2-mercapto-3-phenylpropanoate with nickel(II) and hydrogen ions.
The system formed by 2-mercapto-3-phenylpropanoate (MPP), nickel(II) and hydrogen ions in 30% (v/v) ethanol-water at 25 degrees and I = 100mM (nitrate) has been characterized by means of glass-electrode potentiometry. Protonation constants for 2-mercapto-3-phenylpropanoate and formation constants for the complexes Ni(3)(MPP)(2-)(4) and Ni(MPP)(2-)(2) are reported.
