双三苯基锡2,3-吡嗪二羧酸酯的合成及晶体结构

摘要

A new bistriorganotin(Ⅳ) heterocyclicdicarboxylate{[Ph3Sn(2,3-pdz)SnPh3]2(H2O))was synthesized by the reaction of bistriorganotin(Ⅳ) oxide with 2,3-H2pdz(pdz=pyrazinedicarboxylate). Complex has been characterized by elemental, IR,1H NMR analyses and X-ray crystallographic diffraction analyses. This complex has a 1D supramolecular structure due to the coordinated water molecules via hydrogen bonds to the nitrogen atoms of the pyrazine groups.%利用双三苯基氧化锡与2,3-吡嗪二羧酸反应,合成了新的三有机锡杂环二羧酸酯([Ph3Sn(2,3-pdz)SnPh3]2(H2O)}(pdz=吡嗪二羧酸),并用元素分析、红外光谱、核磁共振氢谱和X-射线单晶衍射对该化合物进行了表征.结果表明,该化合物通过配位水分子和吡嗪氮原子间的氢键作用,形成了一维链状超分子结构.
