Two new 24- and 26-membered macrocycles (L1 and L2) have been prepared from condensation of N 1-[2-(2-aminophenoxy) ethyl]-benzene-1,2-diamine (1), N 1-(3-(2-aminophenoxy) propyl) benzene-1,2-diamine (2) and 2,6- diformyl-4-methylphenol in methanol. The ligands were characterized with various spectroscopic methods such as FT-IR, 1H and 13C NMR and ESI-Mass and elemental analysis. The structure of the L2 has been determined by single-crystal X-ray diffraction analysis. DFT studies at B3LYP/6-31+G(d,p)/GD3 computational level have been carried out and compared to the X-ray results.
