3.4 Molar conductivity measurements

The conductivity Λ<sup>m</sup> value of the La nanocomplexes 1–3 can be calculated by using the relation Λ<sup>m</sup> = K/C. The complexes were (10<sup>3</sup> M) dissolved in DMF, and the molar conductivities of their solutions at 252°C were measured (Table 1). It is concluded from the results that complexes 1 and 3 are found to have molar conductance values of 20.51 and 3.39 ohm<sup>1</sup> mol<sup>1</sup> cm2 , respectively, indicating that these complexes are nonelectrolytic and monomeric in nature. Also the values indicate the bonding of the nitrate ions to metal cations [28, 29]. The molar conductivity value of complex 2 is seen to be 57.88 ohm<sup>1</sup> mol<sup>1</sup> cm2 indicating the ionic nature of this complex, and the nitrate ion is outside the coordination sphere.
