Abstract In this study, the synthesized hydrazine Schiff bases belonging to methyl acetoacetate (1) and α-hydroxyacetophenone (2) were prepared by simple methods. In addition, FT-IR, UV-Vis, 1H NMR, Mass spectra, along with melting point and conductivity measurements were used for the characterization of these compounds. The molecular structures of (1) and (2) were determined by single crystal X-ray
摘要 本研究通过简单的方法合成了属于乙酰乙酸甲酯(1)和α-羟基苯乙酮(2)的肼席夫碱。此外,还使用 FT-IR、UV-Vis、1H NMR、质谱以及熔点和电导率测量来表征这些化合物。(1)和(2)的分子结构通过单晶X射线衍射技术确定。X射线衍射分析表明(1)在正交晶系中结晶,Pca21空间群具有a = 21.1032(12), b = 5.9061(3), c = 10.9717(7), β = 90°而化合物(2)在具有 P21/c 空间群和 a = 7.0386(14), b = 13.275(3), c = 15.071(3), β = 99.27(3)°的单斜晶系中结晶。此外,理论研究是在密度泛函理论 (DFT) 框架内进行的。使用 B3LYP 方法和 (6-311+G (d, p)) 基组对肼化合物 (1) 和 (2) 进行几何优化。计算出的几何参数与实验值吻合良好。DFT
