Abstract: | A new macrocyclic ligand, 1,3,5-triaza-2,4:7,8:19,20-tribenzo-9,12,15,18-tetraoxacyclounkosa-1,5-diene (L) was synthesized
by reaction of 2,6-diaminopyridine and 1,10-bis(2-formylphenyl)-1,4,7,10-tetraoxadecane. Then, its CuII, NiII, PbII, CoIII and LaIII complexes were synthesized by the template effect by reaction of 2,6-diaminopyridine and 1,10-bis(2-formylphenyl)-1,4,7,10-tetraoxadecane
and Cu(NO3)2· 3H2O, Ni(NO3)2· 6H2O, Pb(NO3)2, Co(NO3)2· 6H2O, La(NO3)3·6H2O respectively. The ligand and its metal complexes have been characterized by elemental analysis, IR, 1H and 13C NMR, u.v–vis spectra, magnetic susceptibility, conductivity measurements and mass spectra. All complexes are diamagnetic
and the CuII complex is binuclear. The CoIII complex was oxidized to CoIII. |
