Tetraazamacrocyclic ligands and their copper complexes
Published 1982“…For the 15-membered macrocycle, 18,19,20,21-tetrahydro-17-H-tribenzo(f,j,n)(1,5,9,12)tetraazacyclopentadecine, derivatives bearing different substituents in one of the benzene rings were prepared. For the diimine ligands of this type both cationic and neutral copper(II) complexes were isolated and characterised; (the latter type result from loss of anilino protons on complex formation.) …”
