A [2×2] Fe4grid complex featuring two orthogonal switching modes, namely stepwise spin‐crossover and sequential redox processes, is presented by F. Meyer and co‐workers in their Communication on page 9274 ff. Of particular interest are the resulting twofold‐degenerate configurations [HS‐LS‐HS‐LS] and [Fe II 2 Fe III 2 ], where two identical metal centers occupy opposite corners of the Fe 4 square. Such an arrangement qualifies this new grid complex as a potential building block for quantum cellular automata.
