Conclusions
In this work, a novel 14 membered tetraaza macrocyclic complex has been synthesized in a one – pot
reaction by ethylenediamine, butylamine, formaldehyde and nickel(II) chloride. The formation of the proposed
macrocyclic framework has been confirmed by the appearance of secondary amine bands in the IR and corresponding
crystal structure in the single crystal x-ray diffraction analysis and visible studies. The Ni(II) ion has square-planar
coordination by four nitrogen atoms of the macrocyclic ligand, with weakly coordinated perchlorate ions in
trans
position.
