The title compound, (C21H33N2O)2[SmCl5(C4H8O)]·C7H8·C4H8O, has a layered structure in which each distorted octahedral [SmCl5(THF)]2− unit (THF is tetrahydrofuran) is capped by two cations. The central metal SmIII atom of the [SmCl5(THF)]2− anionic unit is coordinated by five Cl atoms and one THF O atom, forming a distorted octahedral geometry. The crystal structure displays C—HCl and O—HCl hydrogen bonding. The structure exhibits disorder of the solvent.

The anion of the title compound, C5H6N+·C5H2NO4S−, is approximately planar, with the carboxylate and nitro group planes forming dihedral angles of 7.5 (3) and 3.5 (3)°, respectively, with the thiophene ring. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to (011) by N—HO and C—HO hydrogen bonds.
