Multistable molecular materials address fundamental questions in the solid state and promise application in a range of molecular devices. In their Communication on page 10154 ff. C. J. Kepert and co‐workers present a metal–organic framework that exhibits a unique hysteretic three‐step spin‐crossover transition. The transition spans four separate lattice spin states and includes two temperature regions over which the material is formally tristable; that is, three of the four states are stable within each of these regions and may be individually accessed through thermal control.
