Synthesis, Electrochemical and Antimicrobial Studies of Me6-Dibenzotetraazamacrocyclic Complexes of Ni(II) and Cu(II) Metal Ions

Аннотация

Me₆-dibenzotetraaza[14] annulene type macrocyclic complexes of Ni(II) and Cu(II) have been synthesized by template method and characterized by employing various techniques like molar conductance measurement, elemental (C, H, N) analysis, IR, UV-Vis, mass spectra and cyclic voltammetry. On the basis of electronic studies saddle shape distorted octahedral structure have been assigned to these macrocyclic complexes. The redox behavior of Ni(II) and Cu(II) macrocyclic complexes showed reversible and quasiirreversible redox process that supported by the i_pc/i_pa ratio which is in good agreement with Randles-Sevcik equation. These macrocyclic complexes were also studied for the antimicrobial activity against E. coli, P. aeruginosa, B. subtilis, S. aureus and C. albicans compared with Gentamycinas standard drug.
