A Ni(i)Fe(ii) analogue of the Ni-L state of the active site of the [NiFe] hydrogenases

Chem Commun (Camb). 2015 Dec 11;51(95):16988-91. doi: 10.1039/c5cc05881c.

Abstract

[Ni(L(1))Fe((t)BuNC)4](PF6)2 is a robust Ni(II)Fe(II) complex that undergoes a reversible one-electron reduction. Spectroscopic and theoretical studies show that [Ni(L(1))Fe((t)BuNC)4](+) is an unprecedented Ni(I)Fe(II) species that reproduces the electronic configuration of the Ni-L state of the [NiFe] hydrogenases.
