Abstract
Solid complexes of europium picrate with the ligands: 2-(bis-dibutylcarbamoylmethyl-amino)-N,N-dibutyl-acetamid (L1), 2-{bis-[(ethyl-phenyl-carbamoyl)-methyl]-amino}-N-ethyl-N-phenyl-acetamide (L2) and 2-(bis-diethylcarbamoyl methyl-amino)-N,N-diethyl-acetamide (L3) were prepared and characterized by elemental analysis, conductivity measurements and IR spectra. For the [Eu(pic)3L1], X-ray measurements show that the screw coordination arrangement of the achiral tripod-type ligand (L1) around the Eu(III) ion induces the chirality of clockwise (C) and anticlockwise (A) molecular structures. And, the luminescence properties of tripod-type ligands with Eu(III) ion were affected by the complex stereochemistry.
