TLDR
In this paper, the interaction of oxovanadium(IV) with some hydroxy acids, salicylic (SA), 5-sulphosalicylic(SSA), and 8-hydroxyquinoline-5-Sulphonic (HQSA) acids, has been studied potentiometrically.Abstract:
The interaction of oxovanadium(IV) with some hydroxy acids, salicylic (SA), 5-sulphosalicylic (SSA) and 8-hydroxyquinoline-5-sulphonic (HQSA) acids, has been studied potentiometrically. Further, pH-metric studies of the ternary systems, VO2+−HQSA-dicarboxylic or hydroxy acids (where dicarboxylic acids = phthalic and maleic acids and hydroxy acids =SA andSSA) have been carried out and the formation of 1∶1∶1 mixed complexes inferred from the potentiometric curves. The equilibrium, chelate formation and hydrolysis constants have been calculated in the case of binary systems. The ternary complexes have been found to be more stable as indicated by their formation constants.read more

Formation constants of ternary complexes of vanadium(IV) with picolinic acid and salicylic or 5-sulphosalicylic acid.
TL;DR: Potentiometric evidence is presented for the simultaneous addition of both ligands to the metal ion to form the 1:1:1 ternary complex.

Mixed Ligand Chelates of Thorium(IV)
TL;DR: In this paper, mixed ligand chelates of thorium(IV) were prepared in solution and studied potentiometrically, and the results indicated that they may be divided into several classifications, depending on the order in which the ligands coordinate with the metal, on whether or not hydrolysis steps take place, and on whether the system disproportionates into a mixture of complexes each containing one type of ligand.
