A new Hofmann-type metal-organic framework with bent pillar ligand, [Fe(dpoda){Ag(CN)}] (dpoda = 2,5-di-(pyridyl)-1,3,4-oxadiazole), was synthesized. Four-, two- and one-step spin-crossover (SCO) properties were obtained by using different sizes of aromatic guests. Most importantly, hysteretic four-step SCO behaviour with the sequence of LS ↔ HSLS↔ HSLS↔ HSLS↔ HS is observed for the first time.
一种新型的霍夫曼型金属-有机骨架，具有弯曲的支柱配体[Fe(dpoda){Ag(CN)}]（dpoda = 2,5-二（吡啶基）-1,3,4-恶二唑），被合成出来。通过使用不同大小的芳香族客体，得到了四步、两步和一步自旋交叉（SCO）性质。最重要的是，首次观察到具有 LS↔HSLS↔HSLS↔HSLS↔HS 序列的滞后四步 SCO 行为。
