Explanation:

It is basically known that the change in complex compositions of metal play a vital role in the conduction of molecular materials, which display atypical magnetic properties and conducting which also finds applicability in material chemistry, supramolecular and biochemistry, The electrochemical conduct of the nickel Ni(II) complexes was investigated in DMSO by cyclic voltammetry (CV), rotating coulometry and disc electrode (RDE).
