A series of isostructural three-dimensional metal-organic frameworks [Pr2(N-BDC)3(dmf)4]∞ (1), {[Eu2(N-BDC)3(dmf)4]·2DMF}∞ (2·2DMF), [Gd2(N-BDC)3(dmf)4]∞ (3),{[Tb2(NBDC)3(dmf)4]·2DMF}∞ (4·2DMF), {[Dy2(NBDC)3(dmf)4]·2DMF}∞ (5·2DMF) (N-H2BDC = 2-amino-1,4-benzenedicarboxylic acid; DMF = N,N′-dimethylformamide) with cubic 412 · 63 topology have been synthesized using solvothermal conditions. The networks were generated via formation of a dinuclear Ln2 secondary building block, involving the dicarboxylate ligand as a bridge. The luminescent properties of the TbIII and EuIII complexes were studied and showed characteristic emissions at room temperature. Antiferromagnetic interactions between LnIII ions were observed from magnetic susceptibility data.
