Bis[1-(3,5-di-tert-butyl-2-hydroxybenzyl)-3-isopropylimidazolium] pentachlorido(tetrahydrofuran)samarate(III)–tetrahydrofuran–toluene (1/1/1)

Abstract

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—H...Cl and O—H...Cl hydrogen bonding. The structure exhibits disorder of the solvent.
