Abstract: In the title compound, [Sm(C₉I₃O₆)(C₃H₇NO)₃]_n, the Sm^III atom is coordinated by nine O atoms, viz. six carboxylate O atoms from three 2,4,6-triiodobenzene-1,3,5-tricarboxylate (I₃BTC) ligands and three O atoms from three N,N-dimethylformamide (DMF) molecules. Each I₃BTC ligand bridges three Sm^III atoms, generating a three-dimensional metal-organic framework structure. The asymmetric unit contains one Sm^III ion and one I₃BTC anion, both situated on a threefold axis, and one DMF molecule in a general position.
