Abstract: This paper deals with the synthesis and characterization of macrocyclic ligand and its complex compound. Template condensation of chlorocarbons such as 1,1,2,2-tetrachloroethane with 1,3-diaminopropane in presence of nickel (II) or copper (II) yielded the corresponding metal complexes such as 3,7,10,14,15,19,20,24- octaazatricyclotetracosane (OCTC). The macrocyclic ligands and their complexes have been characterized by elemental analysis, molecular weight determination, conductance, IR and NMR spectral studies. The magnetic moments, along with electronic spectral data suggested hexa coordinated state for Nickel, its geometry is outer orbit octa hedral and tetra coordinated state for copper, its geometry is square planner .Conductivity data suggests that they behave as electrolytes. The formulation of the complexes has been established on the basis of chemical composition.

Keywords: Ni (II), Cu (II), Transitional Macrocyclic Complex, Synthesis, Spectroscopy.
