| 摘要: 合成得到了2个新的有机-无机杂化化合物{（4-CH3-Bz-4-Ph-Py）[PbBr3]}n（1）（4-CH3-Bz-4-Ph-Py+=4-甲基苄基-4-苯基吡啶离子）和{（4-F-Bz-4-Ph-Py）[PbBr3]}n（2）（4-F-Bz-4-Ph-Py+=4-氟苄基-4-苯基吡啶离子）。对化合物1和2进行了元素分析、粉末X射线衍射等表征，并利用X射线单晶衍射测定了它们的单晶结构，配合物1与2同构，均属于正交晶系，P21212空间群。结构研究表明，配合物1和2中，铅溴八面体通过共边连接方式，形成[Pb3Br9]n三链，有机阳离子填充在无机溴化铅链空隙中。配合物1和2均未作手性分离。 |

| Abstract: Two homogeneous compounds, {(4-CH3-Bz-4-Ph-Py)[PbBr3]}n (1) (4-CH3-Bz-4-Ph-Py+=4-methylbenzyl-4-phenylpyridinium) and {(4-F-Bz-4-Ph-Py)[PbBr3]}n (2) (4-F-Bz-4-Ph-Py+=4-fluorobenzyl-4-phenylpyridinium), have been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. Compounds 1 and 2 are isostructural, and crystallize in orthorhombic, space group P21212. Structure analyses reveals that haloplumbate ion exhibits octahedron topology in compounds 1 and 2, and all these octahedron topologies formed 1D polymeric chain through edge-sharing connecting modes. The flack values of 1 and 2 are 0.340(13) and 0.453(10), respectively. No chiral separation was done for both compounds. |
