Multistability is exhibited by a metal–organic framework material that undergoes unique three‐step spin crossover with 20 K thermal hysteresis (see picture). The stepwise transition is coupled to a three‐step structural transformation that defines four distinct structural states. The material also exhibits reversible photo‐induced spin crossover.
