Preparation, Characterization and Thermal Study of New Cerium(IV) Complexes with the Salicylidene-2-Aminothiophenol Schiff Base
摘要:
New complexes of the titled Schiff base with cerium(IV) ion have been synthesized and characterized by elemental analyses, conductimetric, IR and H-1 NMR studies and thermogravimetric analysis. The results suggest that the Schiff base acts as a bivalent anion with tridentate ONS donors derived from the phenolic oxygen, azomethine nitrogen and thiophenolic sulfur. The complexes formed are non-electrolytes with the general formulae [ML(NO3)(2)H2O] and [M(HL)(2)(NO3)(2)]. The thermal decomposition of the complexes follows first order kinetics and the thermodynamic parameters of the decomposition are reported.
