Conductance measurements have been made on four neodymium salts: Nd(CF3SO3)3, Nd(ClO4)3, Nd(NO3)3 and NdCl3 dissolved in dimethylformamide. The limiting molar conductivity of Nd(CF3SO3)3 and Nd(ClO4)3 at 25 ℃ calculated by liner fit are 278.8 and 280.7 S•cm2•mol－1 respectively, those of Nd(NO3)3 and NdCl3 obtained by indirect method are 297.2 and 287.3 S•cm2•mol－1 respectively. The electrical conductivity of Nd(CF3SO3)3 and Nd(ClO4)3 increase linearly in the temperature range(25～65)℃. Significant ionic association exists in Nd(NO3)3 and NdCl3 solution.
