A novel derivative 2, 2, 2-tribromo-1- (3,5-dibromo-2-hydroxyphenyl) ethanone was synthesis by “3-acetyl-4-hydroxycoumarin” and dibromide. The structural properties of the synthesized compound have been exploited with the aid of single-crystal X-ray crystallographic studies and infrared spectrometry. The compound crystallizes in the monoclinic system with space group P21/c. A comparative study between
通过“3-乙酰基-4-羟基香豆素”和二溴化物合成了一种新型衍生物2, 2, 2-tribromo-1- (3,5-dibromo-2-hydroxyphenyl) 乙酮。已在单晶 X 射线晶体学研究和红外光谱法的帮助下开发了合成化合物的结构特性。该化合物在空间群为 P2 1 /c的单斜晶系中结晶。介绍了合成的新型溴化化合物与溴化香豆素衍生物之间的比较研究。优化的 DFT 几何形状 (B3PW91/6–311 G (2df, p)) 和比较两个导数的光谱模拟与实验数据非常吻合。Hirshfeld 的分析揭示了 Br ... Br (40%) 和 Br ... H/H ... Br (19%) 在分子堆中总表面接触的重要性。接触 O...H/H...O 对溴化香豆素 ( C2 ) 的贡献为SH 的 26.1%,而溴化循环 ( C1 ) 为 9.7%。
