Artykuł
The template condensation of (R)-2,2¢-diamino-1,1¢-binaphthyl and 2,6-diformylpyridine leads to lanthanide(III)
complexes of the new chiral hexaaza macrocycle L that adopts highly twisted conformation in [LnL](NO3)3
complexes. The complexes have been characterised by ESI MS spectrometry and NMR spectroscopy. The analogous
N2O4 chiral crown ether L2 that has the same carbon skeleton as L does not exhibit tendency to bind
lanthanide(III) ions. The X-ray crystal structure of L2 exhibit squeezed conformation of the macrocycle and spatial
disposition of donor atoms that does not predispose it for coordination of lanthanide(III) ions.
