Thermodynamic considerations in co-ordination. Part XII. Potentiometric and calorimetric investigations of the complexing between the phenylalanate anion and iron(II), iron(III), cobalt(II), nickel(II), and copper(II)

Abstract

Formation constants for AB and A₂B (A = phenylalanate, B = Fe^II and Fe^III, Co^II, Ni^II, and Cu^II) and for Fe^IIA₃, Fe^III₂A₂(OH)₂, and Cu^II₂A₂(OH)₂ are reported for I= 3·00M-(Na⁺)ClO₄^– at 25 °C and corresponding enthalpies and entropies of formation were determined calorimetrically for the Co, Ni, and Cu complexes listed above.
