Solution studies on chelates of nickel, zinc and cadmium with 2-thiopicolinanilide.
The protonation constants of 2-thiopicolinanilide (TPA) and the stability constants of its complexes with Ni, Zn and Cd have been determined potentiometrically in 50% w/w ethanol-water medium, at 25 degrees and 0.100M ionic strength (LiClO(4)). Co-ordination centres in TPA are suggested.
