Two iron(III)compounds exhibited abrupt spin transition with thermal hysteresis loop(T1/2↑=115 K and T1/2↓=104 K for 1・MeOH, and T1/2↑=133 K and T1/2↓=130 K for 1・acetone). Single crystal analysis revealed both of the structures in high-spin(HS)and low-spin(LS)states for 1・acetone. The difference of bond length between the HS and LS states for 1・acetone was~0.10 Å, which was corresponding to that of typical iron(III)SCO compounds. Specially, it showed strong intermolecular interactions by π-π stacking formed between the neighbor complexes leading to 2-D sheet. Both 1・MeOH and 1・acetone exhibited LIESST effect when it was illuminated at 1000 nm. We also confirmed that the introduction of strong intermolecular interactions, such as π-π stacking, can play an important role in LIESST effect., http://link.springer.com/article/10.1007%2Fs10847-011-9960-3}, pages = {363--369}, title = {Photo-switchable spin-crossover iron(III) compound based on intermolecular interactions}, volume = {71}, year = {2011}, yomi = {カミハタ, ヒデノブ and ハヤミ, シンヤ and カミハタ, ヒデノブ and ハヤミ, シンヤ} }
