采用水热法合成了一个新的超分子化合物[PyBImH_2]·[Sn Cl6](Py BIm=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表征。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=2.025g/cm3,Mr=528.63,μ(Mo Kα)=2.395mm~(-1),F(000)=1024,R_1=0.0264,wR_2=0.0665。Sn~(4+)与6个氯离子配位,形成八面体的配位几何。配位阴离子[SnCl_6]~(2-)与阳离子[PyBImH_2]~(2+)通过氢键及π-π堆积作用形成三维超分子结构。
A novel supramolecular compound [PyBImH_2] · [Sn Cl6] (Py BIm = 2- (4-pyridyl) benzimidazole) was synthesized by hydrothermal method and characterized by elemental analysis, infrared spectroscopy, fluorescence spectroscopy and X-ray single Crystal diffraction characterizes it. The compounds belong to the orthorhombic and Pbcn space group with unit cell parameters of a = 7.1468 (3) , b = 15.0493 (6) , c = 16.1195 8, V = 1733.72 133, Z = 4, Dc = 2.025g / cm3, Mr = 528.63, μ (Mo Kα) = 2.395mm -1, F (000) = 1024, R_1 = 0.0264, wR_2 = 0.0665. Sn ~ (4+) coordinates with six chloride ions to form octahedron coordination geometry. The coordination anion [SnCl_6] ~ (2-) and cation [PyBImH_2] ~ (2+) form a three-dimensional supramolecular structure through the hydrogen bonding and π-π stacking.
