Synthesis, structural and thermal characterization and antifungal study of manganese(II), iron(III), cobalt(II) and copper(II) complexes of N,O donor ligands

The solid complexes of MnII, FeIII, CoII and CuII with Schiff bases derived from 3-acetyl-6-methyl-(2H)-pyran- 2,4(3H)dione (dehydroacetic acid) and 3-chloroaniline and 3-aminophenol, have been synthesized and characterized by elemental analysis, conductometry, thermal analysis, magnetic, IR, NMR, UV-Vis spectral studies and X-ray powder diffraction. From the analytical data the stoichiometry of the complexes has been found to be 1:2 (metal:ligand). The low conductance values suggest that the complexes are non-electrolytes. IR spectral data suggest that the ligand behaves as a dibasic bidentate ligand with N:O donor sequence towards metal ions. The kinetic parameters (n, E, Z, ΔS and G) estimated using Coats-Redfern (C.R.), MacCallum-Tanner (M.T.) and Horowitz-Metzger (H.M.) methods are in good mutual agreement. The powder X-ray diffraction itudy suggests that the complex has monoclinic crystal system with P2/m space group. The physico-chemical data suggests that all the complexes possess octahedral geometry. They are also screened for antifungal activity.
