The molar conductance results of the complexes in DMSO showed that the complexes are nonelectrolytes. According to standard Geary reference, 23-45 Ω -1 cm 2 mol -1 is the expected range for 1:1 electrolytes, while below that range represents non electrolytes . The molar conductance of the metal complexes in DMSO were 14.01 and 11.56 Ω -1 cm 2 mol -1 for Ni(II)) and Co(II) complexes respectively.
