Template synthesis and characterization of 12 and 14-membered pendant-armed tetraazamacrocyclic transition metal complexes: A photoelectron spectroscopic study

A new series of 12 and 14-membered tetraazamacrocyclic complexes, [(MLX2)-X-1] and [(MLX2)-X-2] [M = Mn(II), Zn(II), Co(II), Ni(II), X = Cl]; [(MLX2)-X-1] and [(MLX2)-X-2] [M = Cu(II), X = Cl or NO3, L-1 and L-2 = 12 and 14-membered tetraazamacrocyclic ligands] have been prepared via the template condensation of 1,2-dibromoethane or. 1,3-dibromopropane with aniline. The complexes have been characterized by elemental analyses, conductivity, IR, UV-VIS, H-1 NMR, magnetic susceptibility measurements, and x-ray photoelectron spectra. An octahedral geometry has been assigned for all of the prepared metal complexes.
