dc.description.abstract [EN] A binary reversible switch between low-temperature multi-step spin crossover (SCO), through the evolution of the population gamma(HS)(T) with high-spin (HS)-low-spin (LS) sequence: HS1LS0 (state 1) <-> HS2/3LS1/3 (state 2) <-> HS1/2LS1/2 (state 3) <-> HS1/3LS2/3 (state 4) <-> HS0LS1 (state 5), and complete one step hysteretic spin transition featuring 20 K wide thermal hysteresis centred at 290 K occurs in the three-dimensional (3D) Hofmann-type porous coordination polymer {Fe-II(3,8phen)[Au(CN)(2)](2)}center dot xPhNO(2) (3,8phen = 3,8-phenanthroline, PhNO2 = nitrobenzene), made up of two identical interpenetrated pcu-type frameworks. The included PhNO2 guest (x = 1, 1 center dot PhNO2) acts as a molecular wedge between the interpenetrated 3D frameworks via PhNO2-3,8phen intermolecular recognition and is the source of the strong elastic frustration responsible for the multi-step regime. Detailed X-ray single crystal analysis reflects competition between spatial periodicities of structurally inequivalent HS and LS SCO centres featuring: (i) symmetry breaking (state 3) with MIDLINE HORIZONTAL ELLIPSISHS-LSMIDLINE HORIZONTAL ELLIPSIS ordering with gamma(HS) = 1/2; and (ii) occurrence of spatial modulation of the structure providing evidence for stabilization of local or aperiodic ordered mixed spin states for states 2 and 4 (with gamma(HS) approximate to 2/3) and 4 (with gamma(HS) approximate to 1/3), respectively. Below c.a. 20 K, structural and magnetic analyses show the photogeneration of a metastable HS*, state 6. The room-temperature single-step hysteretic regime appears with release of the guest (x = 0, 1) and the elastic frustration, and reversibly switches back to the original four-step behaviour upon guest re-adsorption. Both uncommon relevant SCO events meeting in the same material represent a rare opportunity to compare them in the frame of antiferro- and ferro-elastic transitions. es_ES
