Experimental dynamic viscosity and conductivity data of the air- and water-stable hydrophobic ionic liquids (ILs) N-alkylpyridinium bis(trifluoromethylsulfonyl)imide ([C_npy][NTf₂] n=2, 4, 5) were recorded at temperatures ranging from 298.15 to 338.15 K and from 283.15 to 338.15 K with an interval of 5 K. The dynamic viscosity and conductivity values of the [C_npy][NTf₂] (n=2, 4, 5) ILs were fitted using the Arrhenius equation and the Fulcher equation. The molar conductivity was calculated at temperatures ranging from 283.15 to 338.15 K from the conductivity and density data. The relationship between the dynamic viscosity and the molar conductivity was discussed in terms of Walden's rule.
