Abstract
Copper(II) complexes (CuL2) of the Schiff bases (LH) derived
from 4-phenyl-2-aminothiazole and o-hydroxyaldehydes have been,
characterized by thermogravimetric analysis and powder X-ray diffraction
studies. The TG curves are critically analysed to evaluate
the various methods such as Freeman-Carroll, Coats-Redfern, MacCallum-
Tanner, Horowitz-Metzger and Zsako. The values of kinetic
parameters calculated by these methods are in good mutual agreement.
A tetragonal crystal system is proposed on the basis of X-ray
diffraction studies. Various X-ray parameters (lattice parameters,
volume of unit cell and particle size) are calculated.
