Abstract: 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.
