| 中文摘要: |
| 通过水热法合成了一个新的超分子化合物[PyBImH2]?[SnCl6] (PyBIm=2-(4-吡啶基)苯并咪唑), 并用元素分析、红外光谱、荧光光谱及X射线单晶衍射对其进行了分析测试。化合物属于正交晶系,Pbcn空间群,晶胞参数：a = 7.1468(3),b = 15.0493(6),c = 16.1195(8) ?,V = 1733.72(13) ?3,Z = 4,Dc = 2.025 g/cm3,Mr = 528.63,μ(MoKα) = 2.395 mm-1,F(000) = 1024,R1= 0.0264,wR2 = 0.0665。Sn4+与6个氯离子配位,形成八面体的配位几何。配位阴离子[SnCl6]2-与[2-(4-吡啶基)苯并咪唑阳离子通过氢键及π-π 堆积作用形成三维超分子结构。 |
| 英文摘要: |
| One new supermolecular compound [2-(4-pyridyl)benzimidazoleH2].[SnCl6] has been synthesized and characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. The compound crystallizes in orthorhombic Pbcn space group with the crystal cell parameters: a = 7.1468(3), b = 15.0493(6), c = 16.1195(8) ?, V = 1733.72(13) ?3, Z = 4, Dc = 2.025 g/cm3, Mr = 528.63, μ(MoKα) = 2.395 mm-1, F(000) = 1024. The final R1 = 0.0264 and wR2= 0.0665. Sn4 ion is coordinated by six chloride ions in an octahedron geometry. [SnCl6]2- anions and [2-(4-pyridyl)benzimidazoleH2]2 cations are linked together via hydrogen bonds and π-π stacking ineractions, forming a three-dimensional supermolecular framework. |
