Abstract

Metal-containing ionic liquids composed of the 2,8-dioxo-5-azoniaspiro[4.5]decane (MorphOx) and 2-oxo-5-azoniaspiro[4.4]nonane (PyrOx) spiro cations and tetrachlorometallate anions \({\text{MCl}}_{4}^{{2 - }}\) (M = Mn, Ni, Co) were synthesized and studied by X-ray diffraction (CIF file CCDC nos. 2033482 (Morph-Ox₂CoCl₄), 2033483 (PyrOx₂CoCl₄), 2033484 (PyrOx₂MnCl₄), and 2033485 (PyrOx₂NiCl₄)). The compounds PyrOx₂MCl₄ are isostructural. The phase transition temperatures of the compounds were determined by differential scanning calorimetry.
