Abstract

New series of manganese(II), cobalt(II), nickel(II), copper(II) and cadmium(II) complexes with L1 and L2 bi dentate ligands of 3-acetylcoumarine were prepared and fully characterized by elemental analyses, FT-IR, UV-Visible as well as the magnetic moments and molar conductivity measurements were carried to conclude the geometry of the prepare complexes. The results obtained from H NMR and 13C NMR for the freee ligands and their Cd(II) complexes suggested the coordination sites of the new ligands via two nitrogen atoms of imine moiety and carbonyl of L1 and two nitrogen atoms of thiocyane and pyrazine moeity respectively. The octahedral configuration of aal complexes has revealed on the basis of the elemental analyses and spectral data whereas the Cd(II) complexes were tetrahedral. However, the thermal analyses (TG-DTA and DSC) have carried for some selected metal complexes to approve the thermal stability of complexes formation and to confirm their formula structures.
