Bis[1-(3,5-di-tert-butyl-2-hydroxy-benz-yl)-3-isopropyl-imidazolium] penta-chlorido(tetra-hydro-furan)samarate(III)-tetrahydrofuran-toluene (1/1/1).

The title compound, (C(21)H(33)N(2)O)(2)[SmCl(5)(C(4)H(8)O)]·C(7)H(8)·C(4)H(8)O, has a layered structure in which each distorted octa-hedral [SmCl(5)(THF)](2-) unit (THF is tetra-hydro-furan) is capped by two cations. The central metal Sm(III) atom of the [SmCl(5)(THF)](2-) anionic unit is coordinated by five Cl atoms and one THF O atom, forming a distorted octa-hedral geometry. The crystal structure displays C-H⋯Cl and O-H⋯Cl hydrogen bonding. The structure exhibits disorder of the solvent.
