Novel room temperature ionic liquids (RTILs) consisting of methanide anion, 1,1-dicyano-1-propionylmethanide ([DCPC]-), and various cations,  1-ethyl-3-methylimidazolium ([EMIm]+), 1-butyl-3-methylimidazolium ([BMIm]+), 1-ethyl-3-(2-methoxyethyl)imidazolium ([MMEIm]+), and N-ethylpyridinium ([EPy]+), have been  prepared. The physical and electrochemical properties were studied with TGA, DSC, cyclovoltammetry, and AC impedance measurement. All of these ILs have liquid state at room temperature and thermally stable over 200 oC. The ionic conductivities of [EMIm][DCPC] were observed as 8.7 and 27.5 mS cm-1 at 30 and 80 oC, respectively.
