A 2D layered spin crossover complex, [FeIIH3L(Me)]Cl.I3, has been synthesized from the reaction of FeIIICl3, a tripod ligand (H3LMe = tris[2-(((2-methylimidazoyl-4-yl)methylidene)amino)ethyl]amine), and NaI in methanol. The compound showed an abrupt spin transition between the HS (S = 2) and LS (S = 0) states at T(1/2) = 110 K without hysteresis. The crystal structures of the HS and LS states were determined at 180 and 90 K. A 2D layered structure is composed of NH...Cl- hydrogen bonds between the Cl- ion and three neighboring imidazole groups of [FeIIH3LMe]2+. The green light irradiation at 5 K induced the LIESST effect, and the thermal relaxation process from the HS to LS state showed a sigmoid curve at T > 55 K.
一种二维层状自旋交叉配合物[FeIIH3L(Me)]Cl.I3，由FeIIICl3、三脚架配体（H3LMe = 三[2 - (((2 - 甲基咪唑 - 4 - 基)亚甲基)氨基)乙基]胺）和NaI在甲醇中反应合成。该化合物在T(1/2) = 110 K时在高自旋（S = 2）和低自旋（S = 0）状态之间显示出无滞后的突然自旋转变。在180 K和90 K下测定了高自旋和低自旋状态的晶体结构。二维层状结构由Cl - 离子与[FeIIH3LMe]2 + 的三个相邻咪唑基团之间的NH...Cl - 氢键组成。5 K下的绿光照射诱导了光诱导自旋捕陷效应，并且从高自旋到低自旋状态的热弛豫过程在T > 55 K时呈现S形曲线。
