• Two novel Ln-MOFs were synthesized and structurally characterized.
• Compound 2 exhibits new topology.
• Both 1 and 2 display the typical luminescence of Dy3 + ions in the visible region.
Two new lanthanide metal–organic frameworks (Ln-MOFs) based on Dy(III) binuclear nodes, with formulas {[NH2(CH3)2][Dy2(FDA)3(NO3)]·CH2Cl2·H2O}n (1) and [Dy2(FDA)2(ox)(glycol)2]n (2) (H2FDA = furan-2,5-dicarboxylic acid), are synthesized and structurally characterized. The building blocks of two MOFs are both binuclear clusters stabilized by carboxylic groups, but the architectures are different. MOF 1 is a rare 3,9-connected FEZNUU net with point symbol of (4.62)(410.617.89)(43), whereas MOF 2 exhibits a new topology, in which a four nodes 4,4,5,5-connected net with the point symbols of (43.52.6)(43.53.62.72), respectively. Moreover, luminescence investigation of 1 and 2 shows intense and characteristic emission bands of Dy(III) ions in the solid state.

Moreover, the luminescence properties of compounds were investigated.Figure optionsDownload as PowerPoint slide
