In this work, two Ni(II) complexes with the tetradentate ligand N2S2 (pdto=1,8-bis(2-pyridyl)-3,6-dithioctane,) and the hexa-dentate ligand N6 (bdahp= 2,9-bis-(2’,5’-diazahexanyl)-1,10-phenan-throline) were prepared in order to explore its electrochemical behavior, that indicate their potential use as molecular catalysts for the hydrogen evolution reaction. The Ni(II)-pdto complex presented two consecutive one electron transfer [Ni(ΙΙ)-(pdto)] + 1e- [Ni(Ι)-(pd-to)] and [Ni(Ι)-(pdto)] + 1 e- → Ni(0) + pdto. On the other hand the Ni(II)-bdahp complex presented the electrochemical reduction Ni(ΙΙ)-(bdahp) + 1e- Ni(Ι)-(bdahp) followed by a coupled chemical reaction in an ECi mechanism, where a de-coordination of the diimin-ic moiety of the bdahp ligand was proposed. It was demonstrated that the pdto ligand promotes reduction over Ni(II) at less negative reduc-tion potential in comparison when the ligand bdahp is presented.
