Abstract

We have performed ionothermal reactions between Zn(NO₃) ₂ and H₃BTC in 1-alkyl-3-methylimidazolium bromide ionic liquids with the alkyl group varying from ethyl to amyl. Six 3-D metal-organic frameworks (MOFs), including two isomeric compounds [Zn₃(BTC) ₂(H₂O)₂]·2H₂O (1 and 2) (H₃BTC = 1,3,5-benzenetricarboxylate acid), [EMI]-[Zn(BTC)] (3) (E = ethyl, MI = 3-methylimidazolium), [PMI][Zn(BTC)](4) (P = propyl), [BMI] ₂[Zn₄(BTC)₃(OH)-(H₂O)₃] (5) (B = butyl), and [AMI][Zn₂(BTC)(OH)Br] (6) (A = amyl), have been synthesized and structurally characterized. Compounds 1 and 2 are isomeric compounds, in which the coordination modes of Zn atoms and the BTC^3- ligands are considerably different. Compounds 3-6 crystallize with the corresponding ionic liquid cations incorporated in the frameworks. Their crystal structures show various features including various coordination geometries of Zn²⁺ and various bridging modes of the BTC^3- ligands. The incorporated cations appear to have strong interactions with the frameworks.
