hydrazine-1-carbothioamide (4), N'-piperidine-(5-acetylbarbituric)-1-carbothiohydrazide (5) and N'-hexamethyleneimine-(5-acetylbarbituric)-1-carbothiohydrazide (6), has been synthesized from 5-acetylbarbituric acid and N-unsubstituted/substituted thiosemicarbazides. The synthesized compounds were well characterized by elemental analyses, FT-IR, 1H, 13C NMR and mass spectroscopic methods. Three-dimensional
一系列新的基于 5-乙酰巴比妥的缩氨基硫脲 (TSC) 名为 5-乙酰巴比妥 hydrazine-1-carbothioamide ( 1 )、N-methyl-(5-acetylbarbituric)hydrazine-1-carbothioamide ( 2 )、N-ethyl-(5-乙酰巴比妥)肼-1-碳硫酰肼( 3 )、N,N-二甲基-(5-乙酰巴比妥)肼-1-碳硫酰胺( 4 )、N'-哌啶-(5-乙酰巴比妥)-1-碳硫酰肼( 5 )和N '-六亚甲基亚胺-(5-乙酰巴比妥酸)-1-碳硫酰肼( 6 ),由 5-乙酰巴比妥酸和 N-未取代/取代的氨基硫脲合成。合成的化合物通过元素分析、FT-IR、1 H、13C NMR和质谱法。用单晶X射线晶体学测定了三种化合物(1 •DMSO、2和6 •H 2 O)的三维分子结构,并对其超分子结构进行了分析。还使用 Hirshfeld 表面分析研究了
