The reactions of pyridine-2,6-dicarboxamide with europium(III) and terbium(III) triflates led to the formation of mononuclear complexes of formula [Ln(pcam)3](CF3SO3)3 (Ln = Eu 1, Tb 2; pcam stands for pyridine-2,6-dicarboxamide). From single-crystal X-ray diffraction analysis, the complexes were found to be isomorphous and isostructural. The [Ln(pcam)3]3+ cations and triflate counterions are connected by intermolecular hydrogen bonds, resulting in a 3D network structure. Both the europium(III) and terbium(III) complexes exhibit efficient ligand sensitized luminescence in the visible region with lifetimes of 1.9 ms and 2.2 ms, respectively, in the solid state.
The reactions of the pyridine-2,6-dicarboxamide with europium(III) and terbium(III) triflates give mononuclear complexes of formula [Ln(pcam)3](CF3SO3)3 (Ln = Eu, Tb) that show efficient ligand sensitized luminescence in the visible region.Figure optionsDownload as PowerPoint slide
