三苯基锗2-呋喃甲酸酯的合成和晶体结构研究(英文)

Synthesis and Crystal Structure of Triphenylgermanium(Ⅳ) 2-Furanylcarboxylate Ester

合成了三苯基锗杂环羧酸酯 Ph3Ge O2 CR(R=2 -呋喃基 ) ,利用元素分析、红外光谱、核磁共振氢谱和 X-射线表征了化合物的结构 .该晶体属于单斜晶系 ,空间群为 P2 1/ c,a=1 .1 945(4) ,b=0 .9934(3) ,c=1 .62 84(5) nm,β=91 .59(5) ,Z=4.中心原子锗为四配位形式 .

The complex Ph 3GeO 2CR(R=2\|furanyl) were synthesized by the reaction of sodium 2\|furanyl carboxylate with the triphenylgermanium(Ⅳ) chloride.It was characterized by elemental analysis,IR, 1H NMR and X\|ray single crystal diffraction.The crystal belongs to monoclinic with space group P2 1/c,a=1.194 5(4),b=0.993 4(3),c=1.628 4(5), nm,β=91.59(5),Z=4.In this crystal,the structure consists of discrete molecule containing four\|coordinate germanium atom in a distred tetrahedron.\;
