Two complexes of the type [M(C16 H32 N4)][ZnCl4] , where M=Ni(II), or Co(II) , which belong to the tetra dentate [N4] macrocyclic complexes classes, These complexes were synthesized in methanol media using the template method, in which 1,4-diamino butane was condensed with 2,3-butanedione in the presence of metal salts. The complexes were identified using a variety of spectral and physical techniques, including C.H.N, UV-vis spectroscopy, and mass spectroscopy, FTIR spectroscopy, flammable atomic absorption spectroscopy, conductance, and HNMR spectroscopy. The magnetic susceptibility and molar conductivity for the prepared complexes were measured, from the result data we found the stiocheometrical structure of the complexes has been found to be (1:2:2) (metal: ligand1: ligand2) ratio, and two complexes has ionic behavior, and had no magnetic properties. The spectral studies proved the cyclic structure of the ligand and the complexes, and proved that the tetra linkage was from the cyclic nitrogen atom, the graphic abstract illustrate the preparation process.
