A solution of benzene-1,4-dicarboxylic acid (2 mmol, 0.324 g) in DMF (8 mL) was added to a solution of Zn(NO3)26H2O (2 mmol, 0.582 g) in DMF (2 mL). The mixture was heated in an autoclave for 4 days at 381 K. Cooling of the vessel to room temperature resulted at first in two types of macroscopically similar colourless single crystals (1 and 2) suitable for X-ray analysis. The sample was kept in the solvent due to sensitivity to exposure in air. The synthesis batch was re-examined after 12 months, and a single crystal of MOF-2 was picked from the solution. |

將苯-1,4-二酸(2 mmol, 0.324 g)的DMF(8ml)溶液加入到Zn(NO3)26H2O (2 mmol, 0.582 g) 的DMF (2 mL)溶液中;旌先芤褐糜诟邏悍磻屑訜岬381k,放置4天。 將試劑冷卻到室溫,首先會形成兩種宏觀形貌類似的無色單晶(暫命名1與2),兩種單晶都可以用DRD進行分析。因為樣品對空氣敏感,所以必須保存在溶劑中。保存12個月后重新檢查合成物,溶液中僅可獲得一種晶體,即MOF-2。 |
