FIELD: chemistry.

SUBSTANCE: invention relates to ionic liquid used in electrical energy accumulation devices and as a solvent which contains a cation of general formula where X¹, X² and X³ denote N, O, S or C; R¹-R¹¹, X¹, R¹, R² and R³, X², R⁶, R⁷ and R⁸, X³, R⁹, R¹⁰ and R¹¹ can form ring structures; the anion is selected from [RSO₃]^-, [RfSO₃]^-, [(RfSO₂)₂N]^-, [(RfSO₂)₃C]^-, [(FSO₂)₃C]^-, [ROSO₃]^-, [RC(O)O]^-, [RfC(O)O]^-, [CCl₃C(O)O]^-, [(CN)₃C]^-, [(CN)₂CR]^-, [(RO(O)C)₂CR]^-, [R₂P(O)O]^-, [RP(O)O₂]^2-, [(RO)₂P(O)O]^-, [(RO)P(O)O₂]^2-, [(RO)(R)P(O)O]-, [Rf₂P(O)O]-, [RfP(O)O2]^2-, [B(OR)₄]^-, [N(CN)₂]^-, [AlCl₄]^-, PF₆ ^-, [RfPF₅]^-, BF₄ ^-, [RfBF₃]^-, SO₄ ^2-, HSO₄-, NO₃- I-, bis(oxalate)borate; R, R¹-R¹¹ are selected from hydrogehn, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl and heterocyclyl, halogen, CN- or NO₂-; the carbon in R and R¹-R¹¹ can be substituted with O-, -Si(R')₂-, -C(O)-, -C(O)O-, -S-, -S(O)-, -SO₂-, -SO₃-, -N= -N=N-, -NH-, -NR'-, -N(R')₂-, -PR'-, -P(O)R₄ -P(O)R'-O-, -O-P(O)R'-O- and -P(R')₂=N-; where R' denotes alkyl, fluoroalkyl, cycloalkyl, cycloalkenyl, cycloalkynyl, phenyl or heterocyclyl; Rf denotes a fluorine-containing substitute.

EFFECT: obtaining novel ionic liquids which are stable in liquid state in a wide temperature range.
