Two new cyano-bridged mixed-valence {FeIII2(¦Ì-CN)4FeII2} clusters, {[(Tp)FeIII(CN)3]2[FeII(Py2N2)]2}¡¤(ClO4)2¡¤MeCN¡¤Et2O (1¡¤MeCN¡¤Et2O), its solvent-free form (1), and {[(Tp)FeIII(CN)3]2[FeII(Me2Py2N2)]2}¡¤(ClO4)2¡¤5MeOH (2¡¤5MeOH), were obtained [Tp = hydrotris(pyrazol-1-yl)borate; N,N’-bis(2-pyridylmethyl)-N,N’-bis(4-X-benzyl)-1,2-ethanediamine, Py2N2, X = H; Me2Py2N2, X = Me]. Complexes 1 and 2¡¤5MeOH exhibit gradual thermally induced two-step spin-crossover behavior (SCO) at two FeII metal centers, and the transformation of high-spin (HS) to low-spin (LS) FeII ions with temperature was confirmed by a combination of x-ray crystallog., variable-temperature Fourier transform IR, variable-temperature magnetic susceptibility, and 57Fe Moessbauer spectroscopy. Moreover, complexes 1¡¤MeCN¡¤Et2O and 1 exhibit a reversible single-crystal-to-single-crystal transformation, and complex 1 undergoes two-step SCO behavior with T1/2 = 178 and 93 K accompanied by symmetry breaking in the structure. The cyanide-bridged mixed-valence {FeIII2(¦Ì-CN)4FeII2} square cluster exhibits two-step spin-transition behavior, accompanied by symmetry breaking and single-crystal-to-single-crystal transformation.
