CoII NiII CuII And CrIII Complexes Of Heterocyclic Schiff Base Ligand Synthesis Spectroscopic And Thermal Study

In the present atudy the Schiff base ligand was synthesized by condensing 13-chloro-6-hydroxy-2-methylethanone with chlobenzaldehyde. From this ligand new transition metal complexes of CoII NiII CuII and CrIII with a Schiff base ligand 3-3-chloro-6-hydroxy-2-methylphenyl-5-4-chlorophenyl-45-dihydro-1H-pyrazol-1-ylpyridin-4-ylmethanone were synthesized and characterized on the basis of elemental 1H NMR IR Mass Electronic Spectra and molar conductance data. The thermal data has been investigated to observed degradation pattern and kinetic parameters Entropy Change S Free Energy Change F and Frequency Factor Z were calculated using Freemann-Carol and Sharp-Wentwoth method.
