Anionic zinc-trimesic acid MOFs with unusual topologies: Reversible hydration studies
Journal article, 2010
The reaction of 1,3,5-benzenetricarboxylic acid (H3BTC) with ZnSO4 center dot 6H(2)O in a DMF-water solution afforded two new metal-organic frameworks [Zn-6(mu(3)-OH)(2)(BTC)(4)(DMF)(2.5)(H2O)(2)]center dot[Zn(H2O)(3)(DMF)(3)]center dot 3.1H(2)O (1) and Zn-2(HBTC)(BTC)(H2O)(3)]center dot DMA center dot 3H(2)O (2). Both compounds are thermally stable and can be prepared reproducibly. Rehydration experiments on compound 2 demonstrate reversible dehydration and rehydration while 1 rehydrates to a different crystalline material. Network analysis revealed a binodal (3,6)-net for 1 and a (3,5)-net for 2, both rare topologies.
