Abstract

Two new lanthanide coordination polymers {[Eu2(BDOA)3(H2O)2] · 2H2O}n (1) and {[Er2(BDOA)3(H2O)2]}n (2) were synthesized by treating the corresponding lanthanide(III) chloride and a flexible ligand benzene-1,4-dioxyacetic acid (H2-BDOA). Single-crystal X-ray studies reveal that the ligand BDOA2− adopts different coordination modes in these complexes. Self-assemblies between these bridging ligands and metal ions result in different three-dimensional coordination polymers. The luminescence property of 1 was investigated in the solid state at room temperature.

Graphical abstractFlexible ligand benzene-1,4-dioxyacetic acid adopts different coordination modes along with the changes of the metal radii: (μ2 − η1:η1 + μ2 − η1:η1:η1) and (μ2 − η2:η1 + μ2 − η2:η1) bridging modes in 1, or (μ2 − η1:η1 + μ1 − η1:η1) and (μ2 − η1:η1:η1 + μ2 − η1:η1:η1) bridging modes in 2.Figure optionsDownload full-size imageDownload as PowerPoint slide
