dc.description.abstract | Two polymorphs of the spin crossover (SCO) compound [Fe(1,3bpp)2](ClO4)2 (1 and 2; 1,3bpp, 2-(pyrazol-1-yl)-6-(pyrazol-3-yl)-pyridine) are prepared using a novel, stepwise procedure. Crystals of 1 deposit from dry solvents while 2 is obtained from a solid-state procedure, by sequentially removing lattice H2O molecules from the solvatomorph [Fe(1,3bpp)2](ClO4)2·2H2O (2·2H2O), using single-crystal-to-single-crystal (SCSC) transformations. Hydrate 2·2H2O is obtained through the same reaction as 1, now with 2.5% of added water. Compounds 2 and 2·2H2O are unstable in the atmosphere and absorb or lose one equivalent of water, respectively, to both yield the stable solvatomorph [Fe(1,3bpp)2](ClO4)2·H2O (2·H2O), also following SCSC processes. The four derivatives have been characterized by single crystal X-ray diffraction (SCXRD). Furthermore, the homogeneity of the various compounds as well as their SCSC interconversions have been confirmed by powder X-ray diffraction (PXRD). Polymorphs 1/2 exhibit abrupt SCO near room temperature with T1/2↑ = 279/316 K and T1/2↓ = 276/314 K (near 40 K of shift) and different cooperativity. | - |
