| dc.description.abstract | A new multidentate ligand (1, 10-PDOPD), with a 1, 10-phenanthroline backbone was synthesized by the condensation reaction of 1, 10- phenanthroline-5.6-dione (PD) and o-phenylenediamine (OPDA). Ni (II) and Zn (II) complexes were synthesized by direct method. An alternative template method was also applied for the synthesis of Ni (II) and Zn (II) complexes using the respective metal ions and the ligand precursors OPDA and PD with (mole ratio 1:1). The 1H-NMR, 13C-NMR, UV-Vis and elemental analysis were used for the characterization of the ligand. The complexes were structurally studied through AAS, UV-Vis, conductance and magnetic susceptibility measurements. The magnetic susceptibility at RT of all Ni (II) complexes synthesized showed the presence of two unpaired electrons for the metal ion. All complexes are non-electrolytes in DMF solution. Octahedral geometries have been suggested for each of the complexes.
