Özet
Eight macrocyclic complexes have been synthesised by template reaction of (+/-)-trans-1,2-diaminocyclohexane with metal nitrates and 1,10-bis(2-formylphenyl)-1,4,7,10-tetraoxadecane or 1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane, and their structures are proposed on the basis of elemental analysis, FT-IR, UV-Vis, molar conductivity measurements, H-1 The complexes NMR and mass spectra. The metal-to-ligand molar ratios are 1 : 1 in the complexes, which are 1 : 2 electrolytes for Pb(II), Cd(II) and Zn(II) and 1 : 3 electrolytes for La(III)
