| 摘 要： | 利用三苯基氯化锡和现场生成的5-氯水杨醛缩-α-氨基酸钾反应合成了6种三苯基锡N-(5-氯亚水杨基)-α-氨基酸酯1～6, 通过元素分析、IR和NMR对其结构进行了表征. 利用X射线单晶衍射测定了三苯基锡N-(5-氯亚水杨基)缬氨酸酯(3)和三苯基锡N-(5-氯亚水杨基)异亮氨酸酯(5)的晶体结构. 结果表明锡原子是五配位的, 通过单齿羧基氧原子和相邻分子的酚氧原子对锡的配位形成了具有反式-O2SnC3三角双锥结构的一维链状聚合物. |

| Abstract: | Triphenyltin salts of N-(5-chlorosalicylidene)-α-amino acid 1～6 were synthesized by the reaction of triphenyltin chloride with in situ formed Schiff base, potassium salt of N-(5-chlorosalicylidene)- α-amino acid, and characterized by means of elemental analysis, IR and NMR spectra. The crystal structures of triphenyltin N-(5-chlorosalicylidene)valinate (3) and triphenyltin N-(5-chlorosalicylidene)-isoleucinate (5) were reported. The X-ray structures reveal that the tin atom is five-coordinated and adopts a polymeric trans-O2SnC3 trigonal bipyramidal configuration with the axial positions occupied by a carboxylate oxygen from the ligand and the phenolic oxygen of the ligand in an adjacent complex. |
| Keywords: | triphenyltin(IV) 5-chlorosalicylic aldehyde α-amino acid Schiff base crystal structure |
