StructuralSupramolecular isomers of lanthanide(III): Synthesis, crystal structures and luminescent properties

Résumé

Six lanthanide coordination polymers La2(1,4-BDOA)2(OX)(H2O) (1), Ln2(1,4-BDOA)2(OX)(H2O) [Ln = La (2); Ln = Pr (3); Ln = Sm (4); Ln = Eu (5); Ln = Tb (6)], [BDOA = benzene-1,4-dioxydiacetate; OX = oxalate] had been prepared under hydrothermal conditions, which were characterized by elemental analysis, infrared spectroscopy, thermogravimetric analysis, and single-crystal X-ray diffraction. Compounds 1– 6 crystallize in a triclinic system, space group P1; compounds 1 and 2 are true structural supramolecular isomers based on BDOA ligands constructed from different acid effects; compounds 2–5 are isostructural and exhibit new 3D 12-connected topological networks, which are the same as the topological structure of 6, while 1 shows another 3D 11-connected topological architecture. Furthermore, the luminescent properties of 5 and 6 were studied.
