Synthesis and characterization of bis(macrocyclic) nickel(II) complexes containing aromatic nitrogen-nitrogen linkers produced by template condensation

摘要

Bis(macrocyclic)dinickel(II) complexes containing phenylene bridges between 16-membered pentaaza macrocyclic subunits have been synthesized via one-pot template condensation of nitrogen-nitrogen linker (1,4-phenylenedi-amine;benzidine;4,4'-diaminodiphenylmethane;4,4'-diaminodiphenylether;4,4'-diaminodiphenylsulfone),formaldehyde,1,3-diaminopropane,nickel(II) and 2,4-pentanedione in a 1:4:4:2:2 molar ratio.Elemental analyses,i.r.,u.v.-vis,H-n.m.r.spectroscopy,cyclic voltametry,conductometric and magnetic measurements have been used to characterize the new complexes.
