Syntheses, structures, photoluminescence and magnetic properties of 1D lanthanide chains featuring 2,2′-bipyridine-5-carboxylic ligands

Three isostructural lanthanide(III) complexes all have the 1D chain-like structures, which contain di-nuclear lanthanide(III) units. The photoluminescent properties of 1 and 3 show the ligand L− can effectively transfer energy to lanthanide ions.76
