EPR-spectroelectrochemistry of nickel–organic complexes—small molecules activators

GRAPHICAL ABSTRACT

ABSTRACT

Stable Ni(I) form plays a fundamental role in enzymes (hydrogenase, M-methyl reductase). Information about the catalyst's active form is rare in the literature. The main goal of our investigation is registration EPR spectra and studying the main EPR charactestics of Ni(I) oxidation state of complex with P^Ph₂N^p-Tol₂ ligands which is forming at the potential of Ni(II/I) electrochemical peak.
