Abstract
The title complexes were prepared, and their redox and catalytic properties in hydrogen evolution reaction were examined. The catalytic current increases in the presence of a proton source near the potential of the nickel(I/0) couple for a mixture of nickel(II) complexes with different ligands. Moreover, the catalytic activity of mixed-ligand complexes in the hydrogen evolution reaction was higher than that of a bis-chelated diphosphine nickel(II) complex.
