A chiral 2,6-bis(oxazolinyl)pyridine ligand with amide groups to form isomorphous complexes through all the lanthanoid series.

We newly synthesized the chiral pybox ligand, 2,6-bis[(4S)-tert-butylcarbamoyl-2-oxazolin-2-yl]pyridine, whose lanthanoid(III) complexes have formed isomorphous crystals through all the lanthanoid series. The luminescence properties of the Eu(III) complex have been investigated.
