- Abstract
The crystal structure of the macrobicyclic europium(III) complex [Eu3+ ⊂ 1]3Cl− incorporating a N, N′ - dioxide unit has been determined. It confirms the cryptate nature of this species, the included cation being bound to six N- and two O-sites. The efficient shielding of the bound Eu3+ ion may be related to the efficient luminescence of this cryptate and points to the role played by the N-oxide sites. To further explore the effect of such binding groups, the two macrocyclic ligands 4 and 5 bearing two bipyridine N, N′ -dioxide lateral arms have been synthesized and their EuIII and TbIII complexes prepared.
