Template Synthesis and Characterization of 12 and 14‐Membered Pendant‐Armed Tetraazamacrocyclic Transition Metal Complexes: A Photoelectron Spectroscopic Study

Abstract A new series of 12 and 14‐membered tetraazamacrocyclic complexes, [ML1X2] and [ML2X2] [M = Mn(II), Zn(II), Co(II), Ni(II), X = Cl]; [ML1X2] and [ML2X2] [M = Cu(II), X = Cl or NO3, L1 and L2 = 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, 1H NMR, magnetic susceptibility measurements, and x‐ray photoelectron spectra. An octahedral geometry has been assigned for all of the prepared metal complexes.
