| Abstract: The nine phenylgermanium derivatives of furfuryl carboxylic acid were synthesized by reaction of triphenylgermanium chloride and diphenylgermanium dichloride with sodium furfuryl carboxylate. Their structure were characterized by elemental analysis, IR,1H NMR and MS. The crystal structure of triphenylgermanium 2-furoate was determined by X-ray single crystal diffraction. The crystal belongs to monoclinic with space group P21/c,a=1.1945(4)nm,b=0.9934(3)nm,c=1.6284(5)nm,β=91.59(5)°,V=1.9317(11)nm3,Dcal=1.427Mg·m-3,F(000)=848,Z=4. The germanium atom in this structure is in a distorted tetrahedron. |
