Artykuł
The two new chiral macrocyclic complexes obtained in a template condensation of R,R-1,2-diaminocyclohexane and 2,6-diformylpyridine, [NdL](NO3)3 and [TmL](NO3)3, have been synthesized and their X-ray crystal structures have been determined. The lanthanide(III) ions in both complexes are coordinated by a helically twisted hexadentate macrocycle and two bidentate nitrate anions. The [NdL](NO3)3 and [TmL](NO3)3 complexes have been studied also by 1H and 13C NMR spectroscopy. The signal assignment was based on COSY, NOESY and HMQC measurements. The spectra of the investigated compounds in methanol–chloroform solution confirm the D2-symmetrical helical conformation of the ligand.
