Ph_3SnO_2C_4H_3S的合成、性质和晶体结构

Synthesis and Crystal Structure of Ph_3SnO_2C_4H_3S

用Ph3SnCl与NaO2C4H3S反应,合成了Ph3SnO2C4H3S,并进行了红外光谱、核磁共振氢谱及质谱表征.X-射线单晶衍射表明,该化合物的晶体是由孤立的分子所组成,四配位的锡原子呈畸变的四面体构型,配体噻吩环上的硫原子和锡原子之间存在弱的配住作用.

Ph_3SnO_2C4H_3S was synthesized by the reaction of Ph3SnCl with NaO2C4H3S and was characterized by IR,1H NMR and MS spectra. The crystal structure was determined by X-ray single crystal diffraction. In the crystals,the structure consist of discrete molecule containing four-coordinate tin atom in a distorted tetrahedral configuration
