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。
A new bistriorganotin (IV) heterocyclicdicarboxylate { [-Ph3Sn (2,3-pdz)SnPh3]2 (H2O) } was synthesized by the reaction of bistriorganotin ( IV ) oxide with 2, 3-Hzpdz ( 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.
