Electrical conductivities of powder samples of five new imidazolium salts of aliphatic dicarboxylic acids (imidazolium malonate (1), imidazolium glutarate (2), imidazolium adipate monohydrate (3), diimidazolium suberate (4), imidazolium sebacate (5) were measured by impedance spectroscopy as a function of temperature. It was found that conductivities increase with temperature. At high temperatures, the lowest conductivity was determined for imidazolium glutarate (10-5 S/m) and the highest - for imidazolium sebacate (10-1 S/m). The correlation between crystal structures of the investigated salts and their ionic conductivities is discussed.
