Three oxidation states (+2, +3, +4) of an octahedral nickel center were stabilized in a newly prepared RhNiRh trinuclear complex, [Ni{Rh(apt) 3 } 2 ] n + (apt=3‐ aminopropanethiolate), in which the nickel center was bound by six thiolato donors sourced from two redox‐inert fac ‐[Rh III (apt) 3 ] octahedral units. The three oxidation states of the octahedral nickel center were fully characterized by single‐crystal X‐ray crystallography, as well as spectroscopic, electrochemical, and magnetic measurements; all three were interconvertible, and the conversion was accompanied by changes in color, magnetism, and Jahn–Teller distortion.
