Stability vs. Activity in Electrocatalytic Hydrogen Production and Magnetic Studies of Mononuclear Labile Cu(II) and Ni(II) Complexes

Key Points

• The research aims to investigate the stability and electrocatalytic performance of new Cu and Ni complexes for hydrogen production.
• Synthesis of Schiff base salen-derived complexes [CuII(H2LMe)]·1.5 H2O and [NiII(H2LMe)]·3 H2O.
• Characterization using single crystal X-ray diffractometry and infrared spectroscopy.
• Evaluation of electrocatalytic activity in hydrogen production.
• Both complexes exhibit electrocatalytic activity for hydrogen production.
• Copper complex shows higher activity compared to nickel complex.
• Stability of the complexes was assessed through magnetic studies.
