In the title compound, [Sm(C9I3O6)(C3H7NO)3]n, the SmIII 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 SmIII atoms, generating a three-dimensional metal-organic framework structure. The asymmetric unit contains one SmIII ion and one I3BTC anion, both situated on a threefold axis, and one DMF molecule in a general position.
