Metronidazole (MET-OH), widely used as an antibacterial agent, is found to have some side effects on human bodies. Due to these disadvantages, people have been looking for its modification compounds for substituents. In this article, four MET-OH derivatives were designed, prepared, and structurally characterized by single crystal X-ray diffraction. These compounds are MET-OTs (1), MET-Br (2), MET-Cl (3), and MET-I (4). X-ray structure analyses revealed that, 1 crystallized in the monoclinic system with space group P2 1 /c, with a = 16.1178, b = 7.5473, c = 13.4161 Å, V = 1520.3 Å3, β = 111.3210o and Z = 4. 2 crystallized in the monoclinic system with space group P2 1 /c, with a = 12.079, b = 11.089, c = 6.380 Å, V = 847.1 Å3, β = 97.57o and Z = 4. 3 crystallized in the monoclinic system with space group P2 1 /c, with a = 12.098, b = 11.007, c = 6.295 Å, V = 830.3 Å3, β = 97.886o and Z = 4. 4 crystallized in the triclinic system with space group P1, with a = 6.192, b = 7.740, c = 10.001 Å, V = 457.9 Å3, α = 89.073, β = 86.903, γ = 73.097o and Z = 2. In this article, metronidazole-derived compounds were prepared and structurally characterized by single crystal X-ray diffraction
被广泛用作抗菌剂的甲硝唑(MET-OH)被发现对人体有一些副作用。基于这些缺点,人们一直在寻找其取代基修饰化合物。本文设计、制备了四种 MET-OH 衍生物,并通过单晶 X 射线衍射进行了结构表征。这些化合物分别是 MET-OTs (1)、MET-Br (2)、MET-Cl (3) 和 MET-I (4)。X 射线结构分析表明,1 结晶为单斜晶系,空间群为 P2 1 /c,a = 16。1178,b = 7.5473,c = 13.4161 Å,V = 1520.3 Å3,β = 111.3210o,Z = 4。2 在单斜晶系中结晶,空间群为 P2 1 /c,a = 12.079,b = 11.089,c = 6.380 Å,V = 847.1 Å3,β = 97.57o,Z = 4。 3 在空间群为 P2 1 /c 的单斜晶系中结晶,a = 12。098,b = 11.007,c = 6.295 Å,V = 830.3 Å3,β = 97.886o,Z = 4。4 晶体为三菱系,空间群为 P1,a = 6.192,b = 7.740,c = 10。001 Å,V = 457.9 Å3,α = 89.073,β = 86.903,γ = 73.097o,Z = 2。本文制备了甲硝唑衍生化合物,并通过单晶 X 射线衍射对其进行了结构表征。
