Title: Formation of Fe<sup>IV</sup> and Ni<sup>IV</sup> by Electrochemical and Chemical Oxidation of an Iron‐Substituted Nickel(<scp>II</scp>) Hydroxide: The Direct Two‐Electron Step Ni<sup>II</sup> → Ni<sup>IV</sup> + 2e<sup>−</sup>
Abstract: Six Ni IV ions make up the coordination environment of each Fe IV ion in the γ‐NiOOH‐like layer of the (electrochemically) oxidized form of the iron‐substituted nickel( II ) hydroxide 1 , as can be deduced from Mössbauer spectroscopic and electrochemical investigations. No Ni III ions are present in the redox‐active material. The direct two‐electron step Ni II → Ni IV + 2e − must be assumed. equation image
