PHYSICOCHEMICAL STUDIES AND THERMAL-DECOMPOSITION KINETICS OF COBALT(II) AND NICKEL(II) COMPLEXES OF ACETYLACETONEAMINOFLUORENE

Cobalt(II) and nickel(II) complexes of a new Schiff base, acetylacetone-aminofluorene [LH] have been synthesized. On the basis of spectral, magnetic and thermal data, octahedral structure was assigned to both complexes [ML2(H2O)2]. Thermal decomposition of these complexes was studied by TG. Kinetic parameters, viz. activation energy, E, pre-exponential factor, A, and order of reaction, n, were calculated from the TG curves using mechanistic and non-mechanistic integral equations.
