| Abstract | ||
| Tetradentate macrocyclic ligand (L) having nitrogen and oxygen atoms was prepared by condensation of the diethyl malonate with 4-nitro phenyl hydrazine in ethanol. An ethanolic solution of ligand (L) and an ethanolic solution of 1, 10-phenanthroline were reacted with ethanolic solution of metal salts to give complexes with the general formula [M(L)(phen)]X, where L=N,N-bis(4-nitro phenyl) malonyl dihydrazide, phen= 1,10-phenanthroline and M= Cr(III), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II). The resulting product was solid, which have been characterized using FT-IR and UV-Vis spectroscopy. Elemental analysis have been performed using C.H.N and atomic absorption technique, the magnetic susceptibility and the conductivity have also, been measured. From these measurements, mixed structures of the complexes were proposed to be octahedral geometry and to study the coordination behavior and spectral. | ||
