Abstract

In this work, new Cd2+, and Hg2+ complexes of 4-pyridyl thiosemicarbazon Schiff base derived from beta-hydroxy carbonyl has been synthesized and isolated. The structure of the new complexes was proposed by numerous techniques such as elemental (CHN) analyses, FT-IR. TG and DTG thermal decomposition for Cd2+ complex was carried out. Thermodynamic and kinetic parameters were calculated via Coats-Redfern and Horowitz-Metzger equations. And finally, the modeling using DFT calculations was fully studied.
