| 摘要: 本文以2-氯烟酸为原料合成了2，2′-二硒并烟酸叔丁基酯(1)及2，2′-二硒并烟酸(2)，化合物1和2的结构分别用 1H NMR，13C NMR，77Se NMR，元素分析和X-射线单晶结构测定技术进行了表征。在化合物1和2的晶体结构中，吡啶环和2个硒原子处于同一平面，这一结果与已报道的芳基二硒醚化合物的晶体结构完全不同。 |

| Abstract: 2,2′-diselenobisnicotinic acid tert-butyl ester (1) and 2,2′-diselenobisnicotinic acid (2) were synthesized based on 2-chloronicotinic acid. Compounds 1 and 2 were well characterized by 1H NMR, 13C NMR, 77Se NMR, elemental analysis and X-ray single crystal structural analyses. The crystal structure of compound 1 belongs to triclinic crystal system and P1 space group, and the crystal structure of compound 2 is monoclinic crystal system and P21/c space group. In the crystal structure of 1 or 2, the two selenium atoms and two pyridyls are coplanar, which is very different from the reported crystal structures of diaromatic diselelenide. CCDC: 729953, 1; 729952, 2. |
