三苯基锗2-呋喃甲酸酯的合成和晶体结构研究

摘要

The complex Ph3GeO2CR (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 P21/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.%合成了三苯基锗杂环羧酸酯PhsGeO2CR(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P21/c,a=1.194 5(4),b=0.993 4(3),c=1.628 4(5)nm,β=91.59(5),Z=4.中心原子锗为四配位形式.
