Novel ionic liquids (ILs) composed of azole type cation and anion were prepared. Triazole and tetrazole were coupled with 1-ethyl-3-methylimidazolium hydroxide. Obtained tetrazole salt was liquid at room temperature showing only glass transition temperature at -89 degreesC. The ionic conductivity reached to 8.9 x 10(-3) S cm(-1) at room temperature reflecting low viscosity of 42.5 cP at 25 degreesC. This is the first report on the ILs based on only azole type ions.
