ylthiophene-3-carboxamide (ACPETC) (C10H14N2OS) has been synthesized, characterized via single-crystal X-ray diffraction at 296 K and studied theoretically via DFT approach. The compound crystallizes in tetragonal crystal system, space group I-4 with Z = 8 and the following unit cell dimensions: a = 16.0892(4) Å, b = 16.0892(4) Å, c = 8.4059(2) Å. ACPETC was experimentally characterized by 1H, 13C
已合成2-氨基-N-环丙基-5-乙基噻吩-3-甲酰胺 (ACPETC) (C 10 H 14 N 2 OS),通过 296 K 下的单晶 X 射线衍射表征并通过 DFT 方法进行理论研究。该化合物在四方晶系中结晶,空间群 I-4,Z = 8,晶胞尺寸如下:a = 16.0892(4) Å,b = 16.0892(4) Å,c = 8.4059(2) Å。ACPETC 通过1 H、13 C NMR、FT-IR、UV-Vis 和 ESI-MS 分析进行实验表征。ACPETC (C 10 H 14 N 2使用 HF、MP2、DFT/B3LYP 使用 6-311++G(d,p) 基组估计基态中的 OS)。计算出的 NMR 化学位移(1 H 和13 C)以及 IR 主动振动中的离散区域与其实验对应物非常一致。ACPETC的FT-IR光谱在4000-450 cm -1范围内获得. 已经研究了紫外-可见光谱以及溶剂的影响。估计的
