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.
