A conformationally flexible triazole-carboxylic acid ligand derived from an L-amino acid, namely, 4 H-1,2,4-triazol-4-yl-acetic acid (αHGlytrz), has been exploited to synthesize a structurally diverse and functionally intriguing metal-organic framework with CuSiF6. The crystal structure reveals a novel single-walled metal-organic nanotube (SWMONT), namely, {[Cu3(μ3-OH)(H2O)3(Glytrz)3]⋅SiF6⋅8 H2O⋅X}∞ (1), (where X = disordered lattice water molecules) having a pore size as large as zeolites. Compound 1 was synthesized as crystals, as powder, or as layers by precipitation/electrodeposition. Mercury intrusion porosimetry demonstrates the ability of this material to store metallic mercury, after a pressure treatment, contrary to previous literature examples.
一种由L-氨基酸衍生而来的构象灵活的三唑羧酸配体，即4 H-1,2,4-三唑-4-基乙酸（αHGlytrz），已被用于与CuSiF6合成一种结构多样且功能有趣的金属有机框架。晶体结构揭示了一种新型的单壁金属有机纳米管（SWMONT），即{[Cu3(μ3-OH)(H2O)3(Glytrz)3]⋅SiF6⋅8 H2O⋅X}∞ (1)，（其中X = 无序晶格水分子），其孔径与沸石一样大。化合物1可以通过沉淀/电沉积法合成晶体、粉末或层状。压汞法表明，与之前文献中的例子相反，该材料在经过压力处理后能够储存金属汞。
