... Ni(II) compounds play an important role in material science, catalysis, electrochemistry and medicinal chemistry due to their difference in characteristics and chemical reactivities [14][15][16][17][18]. Moreover, nickel can exhibit variable oxidation states like Ni(0), Ni(I), and Ni(II) [19,20]. Coordination compounds of Ni(II) can exhibit photoluminescence property also [21]. ...
