摘要
The reaction of 1,3,5-benzenetricarboxylic acid (H3BTRI) with ZnSO4 center dot 7H(2)O in DMF and H2O afforded [Zn-2(mu(2)-OH2)(HBTRI)(BTRI)(H2O)(2)]center dot DMA center dot 3H(2)O (1). Compound 1 displays self-healing properties upon dehydration and rehydration as revealed by scanning electron microscopy. Further studies showed that 1 is flexible and able to absorb additional water molecules in high vapor pressure environments. The reaction of H3BTRI with Gd(NO3)(3)center dot 6H(2)O in DMF and H2O resulted in [Gd(BTRI)(H2O)(6)] (2). It is also possible to form compound 2 through a solid-state process when crystals of 1 are placed into a solution of Gd(NO3)(3)center dot 6H(2)O in DMF and H2O. The reverse process does not occur.
