摘要: 报道了一种由氢键及π-π堆积作用构筑的三维网状超分子配合物[Cu(H2L)3]Cl(H2L=N-4-乙氧基苯甲酰基-N′-2-甲氧基苯基硫脲) 的合成, 并通过元素分析、红外光谱、核磁共振谱和单晶X衍射结构分析表征了其组成与结构。标题化合物中每个铜离子与3个硫脲分子中的硫原子及1个氯离子形成四面体型配位,整个分子就如同一个以Cu-Cl键为轴以3个硫脲分子为叶片的旋转着的风车。而每个配合物分子间又通过π-π堆积作用及分子间氢键组装成一个三维网状超分子结构。该化合物晶体属于三方晶系,R3 空间群。 |

Abstract: A three-dimensional supramolecular network [Cu(H2L)3]Cl based on hydrogen bonds and π-π stacking has been synthesized, and characterized by elemental analysis, IR, 1H NMR and X-ray diffraction single crystal structure analysis. the central copper atom is in a tetrahedral geometry contributed by three S and one Cl ion, the overall molecular structure seems like a revolving windmill. The complex molecule is assembled into a three-dimensional netlike supramolecule by hydrogen bonds and π-π stacking. The complex crystallizes in trigonal system, space group R3 with cell dimensions a=1.382 43(7) nm, b=1.382 43(7) nm, c=4.772 6(4) nm, V=7.899 0(8) nm3, Z=3, Dc=1.375 Mg·m-3. CCDC: 734877. |
