Determination of the Protonation Constants of Cycloalkyl Thiophen-Schiff Bases and their Complex Stability Constant with Ni(II) Ion
Abstract :
The protonation constants of the cycloalkyl thiophen-Schiff bases and their stability constants of the Ni(II) complexes were potentiometrically determined in a ethanol–water 50% (w/w) solution at 25°C, under N2 atmosphere and 0.15 M KCl ionic strength. The stoichiometric protonation constants have been measured by the potentiometric titration and calculations were performed by the PKAS computer software recently developed. Variations of the protonation constant of Schiff bases have been discussed in view of structural effects exerted on Ni(II)-complex and antimicrobiyal.
