在用含微量水的苯和氯仿混合溶剂重结晶(M e3S iCH2)2Sn(OCOC6H4NO2-p)2的过程中,得到含硅二烃基锡化合物[(M e3S iCH2)2Sn(OCOC6H4NO2-p)OSn(OH)(M e3S iCH2)2〗2的晶体,通过红外光谱和元素分析对其结构进行了表征。X-射线单晶衍射测定表明,该化合物分子是以Sn2O2四元环为中心的中心对称二聚体结构,内环锡为5配位的畸变三角双锥结构,外环锡也为5配位的畸变三角双锥结构。
In the course of recrystallization of (M e3S iCH2) 2Sn (OCOC6H4NO2-p) 2 with a mixed solvent of benzene and chloroform containing a trace amount of water, a dialkyltin-containing compound [(M e3S iCH2) 2Sn (OCOC6H4NO2-p) OSn OH) (M e3S iCH2) 2〗 2 crystals were characterized by IR and elemental analysis. X-ray single crystal diffraction measurement showed that the compound is a central symmetric dimer structure centered on a Sn2O2 four-membered ring. The inner ring tin is a 5-coordinated distorted triangular bipyramid structure and the outer ring tin is also a 5-coordinated Distorted triangular double cone structure.
