Аннотация

Novel inclusion compounds based on iron(II) tris(pyrazol-1-yl)methane [Fe{HC(pz)₃}₂]²⁺ cation and p-sulfonatocalix[4]arene (C[4]AS) as a counterion of formulas [Fe{HC(pz)₃}₂]₂(C[4]AS)·24H₂O (II) and [Fe{HC(pz)₃}₂]₅(C[4]AS)₂·62H₂O (III) have been synthesized in the solid state and studied by SC-XDR. The inclusion of [Fe{HC(pz)₃}₂]²⁺ cation into the macrocycle cavity with 1:1 host-guest stoichiometry in both cases was found. The magnetochemical investigation (μ_eff) of the dehydrated complex I of formula [Fe{HC(pz)₃}₂]₅(C[4]AS)₂ in the 78–500 K temperature range has shown a high-temperature ¹A₁ ⇔ ⁵T₂ spin crossover (SCO) which was accompanied by thermochromism. The crossover temperature values for heating (T_c↑) and cooling (T_c↓) are equal to 390 K and 380 K, respectively.
