Copper(II) and nickel(II) complexes of an N-pendent bis-(cyanoethyl) derivative of an isomeric hexamethyl tetraazamarocyclic ligand: Synthesis, characterization, electrolytic behavior and antimicrobial studies

New macrocyclic complexes were synthesized by the interaction of nickel(II) and copper(II) salts with a new N-pendent bis-(cyanoethyl) derivative, ‘tet-bx’ of an isomeric hexamethyl tetraazamarocyclic ligand. The compounds were characterized by different analytical and spectroscopic techniques. Antibacterial and antifungal activities of these compounds were tested against some selected gram positive and gram negative bacteria and fungi.
