双三苯基锡2，3-吡嗪二羧酸酯的合成及晶体结构(英文)

Syntheses and Crystal Structure of Bistriphenyltin Pyrazinedicarboxylate

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{[Ph_3Sn(2,3-pdz)SnPh_3]_2(H_2O)}(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.
