The paper reports the study of the photoinduced high spin (HS) state lifetime in a multistep spin crossover compound. Despite the pronounced three‐step transition of the [Fe(dpsme)Pt(CN) 4 ] · 2 / 3 dpsme · x EtOH · y H 2 O {dpsme = 4,4′‐di(pyridylthio)methane; EtOH = ethanol} 3D compound, neither the T (LIESST) nor the relaxation kinetics exhibits stepwise features. From the detailed investigation (experiments and simulations) of these relaxations and the observation of the light‐induced thermal hysteresis, a phase transition around 58 K is suspected.
