在不同有机模板剂存在下，Cu（CH 3COO）2·H2O与吡啶-4，5-咪唑二甲酸（H3 PyImDC）在溶剂热条件下的组装得到了两种三维手性骨架，|（C3H10N2）（C3H7NO）0.5（H2O）2| [CuIIC 10 H5 O 4 N3]（1）和|（C4H9NO）0.5（H2O）8| [CuII2CuI（C10H5O4N3）2（C10H6O4N3）]（2）.这两种化合物的晶体在立方，P4332空间群和具有开放的螺旋通道的框架。据我们所知，化合物1和2呈现具有bmn和lcy-a网的第一合成的M0 F。通过X射线粉末衍射、电感耦合等离子体分析、CHN、红外光谱、荧光光谱、X射线光电子能谱和热重-差热分析等手段对两种化合物进行了表征。
The assembly of Cu(CH3COO)2·H2O and pyridine-4,5-imidazoledicarboxylic acid (H3PyImDC) under solvothermal conditions in the presence of different organic templates yielded two three-dimensional chiral frameworks, |(C3H10N2)(C3H7NO)0.5(H2O)2|[CuIIC10H5O4N3] (1) and |(C4H9NO)0.5(H2O)8|[CuII2CuI(C10H5O4N3)2(C10H6O4N3)] (2). Both of the compounds crystallized in the cubic, P4332 space group and possessed open helical channels in the frameworks. To the best of our knowledge, compounds 1 and 2 present the first synthesized MOFs with a bmn and lcy-a net. Further characterization of the two compounds has been performed, including X-ray powder diffraction, inductively coupled plasma analysis, CHN, IR spectra, fluorescence spectra, X-ray photoelectron spectroscopy spectrum and thermogravimetric-differential thermal analysis.
