Spin-State Patterning in an Iron(II) Tripodal Spin-Crossover Complex
[Image: see text] A mononuclear iron(II) complex that displays a gradual two-step spin-crossover (SCO) transition is reported. The intermediate plateau (IP) occurs between HS(0.40)LS(0.60) and HS(0.30)LS(0.70) (HS = high spin; LS = low spin) ratios over the region of ca. 190–170 K. A phase change oc...

| description | [Image: see text] A mononuclear iron(II) complex that displays a gradual two-step spin-crossover (SCO) transition is reported. The intermediate plateau (IP) occurs between HS(0.40)LS(0.60) and HS(0.30)LS(0.70) (HS = high spin; LS = low spin) ratios over the region of ca. 190–170 K. A phase change occurs at the IP, breaking the symmetry, resulting in six independent SCO sites compared to one at the 100% HS and LS plateau regions, respectively. Variable-temperature X-ray photoelectron spectroscopy shows that the SCO behavior is completely reversible among the HS, IP, and LS regions. The results both confirm and extend the related results for the above system described by Halcrow et al. ( R. Kulmaczewski; O. Cespedes; M. A. HalcrowGradual Thermal Spin-Crossover Mediated By a Reentrant Z′ = 1 → Z′ = 6 → Z′ = 1 Phase Transition, Inorg. Chem. 2017, 56, 3144−314828244751) in a recent report. |
