Abstract

The crystal structures of a flexible metal–organic framework based on Cu^II and 2,3-dhtp in different states of solvation are reported.

Metal–organic frameworks (MOFs) are an exciting class of porous materials with applications in many fields. To find the optimal MOF for every application it is important to synthesize new materials to find those with the desirable properties. Here we present a MOF based on Cu^II and 2,3-dihydroxyterephthalate, whose structure in both fully solvated and partially desolvated forms, namely, poly[[triaqua(μ-2,3-dihydroxyterephthalato)(μ-2,3-dioxidoterephthalato)tricopper(II)] monohydrate], {[Cu₃(C₈H₂O₆)(C₈H₄O₆)(H₂O)₃]·H₂O}_n, and poly[[diaqua(μ-2,3-dihydroxyterephthalato)(μ-2,3-dioxidoterephthalato)tricopper(II)] ethanol monosolvate monohydrate] {[Cu₃(C₈H₂O₆)(C₈H₄O₆)(H₂O)₂]·C₂H₅OH·H₂O}_n, has been solved with single-crystal X-ray diffraction. It shows one-dimensional hexagonal channels and a flexible behaviour in response to changes in solvation.

由CuII和2,3-二羟基对苯二甲酸形成的柔性MOF。

金属有机骨架（mof）是一类令人兴奋的多孔材料，在许多领域都有应用。为了找到各种应用的最佳MOF，重要的是合成新材料，以找到具有理想性能的材料。本文提出了一种基于CuII和2,3-二羟基对苯二甲酸酯的MOF，该MOF具有完全溶剂化和部分脱溶剂化两种结构，即聚[[三水-（μ-2,3-二羟基对苯二甲酸酯）（μ-2,3-二氧对苯二甲酸酯）（μ-2,3-二氧对苯二甲酸酯）三铜（II）]一水合物]、{[Cu3(C8H2O6)(C8H4O6)(H2O)3]·H2O} n和聚[[二水-（μ-2,3-二氧对苯二甲酸酯）（μ-2,3-二氧对苯二甲酸酯）三铜（II）]乙醇一水合物]{[Cu3(C8H2O6)(C8H4O6)(H2O)2]·C2H5OH·H2O} n。用单晶x射线衍射解决。它表现出一维六角形通道和响应溶剂化变化的柔性行为。
