Chiral macrocyclic Nd(III) and Tm(III) complexes
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. (C) 2000 Elsevier Science Ltd.
