摘要
通过溶液挥发法用咪唑溴鎓盐为模板剂与碘化铅反应,合成了有机-无机杂化聚合物1{[(C4H6N2)2C2H4]2Pb3I10}n.通过X-射线单晶衍射测定了其晶体结构,并进行了红外、紫外、元素分析等表征.结构解析表明:该化合物属于三斜晶系,P-1空间群,a=10.4184(17),b=10.959(2),c=12.2760(19),α=113.051(5)°,β=95.050(2)°,γ=115.161(3)°,V=1111.5(3)3,Z=1.该化合物由是由有机阳离子[(C4H6N2)2C2H4]2+和无机聚阴离子链[Pb3I10]n4n-组成的1-D链结构,有机组分与无机组分之间通过氢键作用使整个化合物扩展成二维超分子网状结构.
A new organic-inorganic hybrid polymer 1{[（C4H6N2）2C2H4]2Pb3I10}n was synthesized by solvent evaporation using imidazolium as a structure-directing reagent to react with lead（II） iodide. I was characterized by single crystal X-ray diffraction, IR, UV-Vis Spectra and elementary analysis. Structural analyses show that I belongs to triclinic and P-1 space group with a=10.4184（17）A,b=10.959（2）A,c=12.2760（19）A,α=113.051（5）°,β=95.050（2）°,γ=115.161（3）°,V=1111.5（3）A3,Z=1.1 consists of dication [（C4H6N2）2C2H4]2＋ and inorganic anion [Pb3I10]n4n- to form a 1-D chain structure, which is further interacted by hydrogen bond interactions to form a 2-D supermolecular network.
