**3.6 Molar conductance**

The molar conductance (*Λm*) of the metal complexes was determined by applying the relation *Λm* = 1000 × *κ*/*c*, where *κ* and *c* stands for the specific conductance and molar concentration of metal complexes respectively. The complexes (1 × 10<sup>−</sup><sup>3</sup> M) were dissolved in DMF and their specific conductance was measured at (298.15 *±* 0.01) K. The molar conductance data was observed as 123, 128 and 131S cm<sup>−</sup><sup>1</sup> mol<sup>−</sup><sup>1</sup> for the metal complexes **3a**, **4a** and **5a** respectively indicating their 1:2 electrolytic natures.
