通过Ag（I）与3，5-双（三氟甲基）-1，2，4-三唑反应，得到了一种由三配位Ag（I）中心连接的四核簇[Ag（4）TZ（6）]组成的中性、无氢、扩展的三维纳米管多孔骨架FMOF-1。框架的氟内衬通道和空腔显示出H-2的滞后吸附，在77 K和64 bar下的体积容量为41 kg/m3。该框架还表现出非常高的吸附O-2和N-2与体积吸收类似的550和400公斤/米（3），在77 K，即使在非常低的压力（< 10（-2）巴）。
A fluorous metal-organic framework, FMOF-1, is obtained by reaction of Ag(I) with 3,5-bis(trifluoromethyl)-1,2,4-triazolate, giving rise to a neutral, hydrogen-free, extended 3D nanotubular porous framework consisting of tetranuclear clusters [Ag(4)TZ(6)] connected by three-coordinate Ag(I) centers. The fluoro-lined channels and cavities of the framework show hysteretic adsorption of H-2 with a volumetric capacity of 41 kg/m(3) at 77 K and 64 bar. The framework also exhibits very high adsorptions for O-2 and N-2 with volumetric uptake of similar to 550 and 400 kg/m(3) at 77 K even at very low pressures (< 10(-2) bar).
