将无孔中性骨架[CuCl（2）（m-bttmb）（2）]（n）（1）转变为多孔离子型{[Cu（m-bttmb）（2）（H（2）O）Cl]Cl（CH（3）CN）（0.5）（H（2）O）（2.75）}（n）（2）通过简单地增加混合溶剂（CH（3）CN和H（2）O）中CH（3）CN的量或CuCl（2）·2 H（2）O与1反应的温度，3-双（三唑-1-基甲基）-2，4，6-三甲基苯（m-bttmb）。当用CH（3）CN处理时，1转化为2。1和2都具有2D 4-连接（4，4）网络架构，但具有不同的封装布置。通过单晶X射线衍射分析、元素分析、红外光谱和热重分析对这些化合物进行了表征。这一工作可能提供一种通过调节溶剂的极性和组分来控制中性或离子骨架的形成以及孔隙率的方法。
A nonporous neutral framework [CuCl(2)(m-bttmb)(2)](n) (1) was changed into a porous ionic {[Cu(m-bttmb)(2)(H(2)O)Cl]Cl(CH(3)CN)(0.5)(H(2)O)(2.75)}(n) (2) by simply increasing the amount of CH(3)CN in the mixed solvent (CH(3)CN and H(2)O) or temperature in the reactions of CuCl(2)·2H(2)O with 1,3-bis(triazol-1-ylmethyl)-2,4,6-trimethylbenzene (m-bttmb). 1 undergoes transformation into 2 when treated with CH(3)CN. Both 1 and 2 have 2D 4-connected (4,4) network architectures but in different packing arrangements. These compounds have been characterized by single-crystal X-ray diffraction analysis, elemental analysis, IR spectra and thermogravimetric analysis. This work may provide a way to control the formation of neutral or ionic frameworks, as well as porosities by adjusting the polarity and components of the solvents.
