The chemistry of microporous compounds have been studied extensively due to unique properties such as separation, adsorption, heterogeneous catalysis, and so on. Especially, creation of novel porous materials as adsorbents is a most attractive research field for the purpose of storage and transport of natural gas. A novel 3-D coordination polymer, [{[CuSiF6 (4,4'-bpy)2] 8H2O)}n](4,4'-bpy= 4,4'-bipyridine) was synthesized and characterized. This network provides channels with dimensions of ca 8 Å * 8 Å along the c-axis and ca 6 Å * 2 A along the a- and b-axes. The differential pore volume plot, represented by the HK method, shows only one sharp peak at ca 7.8 Å. The methane adsorption experiment was also carried out on zeolite 5A, which has the highest known methane adsorption capacity. XRPD measurement shows that the network is retained in the absence of any guest molecules in the channels.

微孔化合物因其独特的分离、吸附、多相催化等性能而受到广泛的关注，尤其是新型多孔吸附材料的制备，更是天然气储运领域的研究热点。合成并表征了一种新型三维配位聚合物[{[CuSiF 6（4，4 '-bpy）2] 8H 2 O）}n]（4，4'-bpy= 4，4 '-联吡啶）。该网络提供沿c轴尺寸为约8埃 * 8埃沿着和沿a轴和b轴尺寸为约6埃 * 2埃沿着的通道。由HK方法表示的微分孔体积图仅在约7.8 nm处显示一个尖峰。甲烷吸附实验也在具有最高已知甲烷吸附能力的沸石5A上进行。XRPD测量表明，在通道中不存在任何客体分子的情况下，网络得以保留。
