Novel Ni(II) Tetraaza Macrocyclic Complex : Synthesis and Characterization

Mayura A. Panchbhai and N. S. Bhave

Novel tetraaza macrocyclic ligand has been synthesized from condensation of ethylene diamine and ethyl acetoacetate and its Ni (II) complex is prepared by non-template condensation reaction. The bonding and stereochemistry of the complex has been characterized by elemental analysis, magnetic susceptibility, IR, UV-visible, 1H NMR and mass spectral studies. The magnetic and spectral data indicate octahedral geometry of the complex.
