| 摘 要： | Spin-crossover（SCO） complexes with multiple spin states are promising candidates for high-order magnetic storage and multiple switches. Here, by employing the N,N’-4-dipyridyloxalamide（dpo） ligand, we synthesize two Hofmann-type metal-organic frameworks（MOFs） Fe（dpo）{Ag（CN）2}2]·3DMF（1） and Fe（dpo）{Ag（CN）2}2]·0.5Me CN·2DEF（2）, which exhibit guest dependent four-step SCO behaviors with the sequences of LS → ～LS2/3HS1/3→ LS1/2...

| Abstract: | Spin-crossover (SCO) complexes with multiple spin states are promising candidates for high-order magnetic storage and multiple switches. Here, by employing the N,N?-4-dipyridyloxalamide (dpo) ligand, we synthesize two Hofmann-type metal-organic frameworks (MOFs) Fe(dpo){Ag(CN)2}2]·3DMF (1) and Fe(dpo){Ag(CN)2}2]·0.5MeCN·2DEF (2), which exhibit guest dependent four-step SCO behaviors with the sequences of LS → ～LS2/3HS1/3 → LS1/2HS1/2 → ～LS3/10HS7/10 → HS and LS → ～LS2/3HS1/3 → LS1/2HS1/2 → ～LS1/4HS3/4 → HS, respectively. Therefore, the incorporation of hydrogen-donating/hydrogen-accepting groups into the Hofmann-type MOFs may effectively explore the multi-step SCO materials by tuning hydrogen-bonding interactions. |
