thermal stability was studied by TG-DTA diagrams under argon atmosphere. Furthermore, 3-D Hirshfeld surfaces in combination with 2-D fingerprint plots were carried out. This compound was also evaluated for its antioxidant activity; four tests were done, in vitro, 1,1-diphenyl-2-picrylhydrazyl (DPPH•), hydroxyl scavenging ability (OH•), ferric reducing power (FRP) and ferrous ion chelating (FIC) ability
摘要 在常温常压条件下合成了新型杂化[4-Cl-2-(CH3)C6H3NH3]6P6O18·2H2O。单晶X射线衍射研究用于鉴定其结构。它揭示了这种有机环六磷酸盐在 P 1 ¯ 三斜空间群中结晶,a = 10.41 (10) A b = 10.94 (7) A, c = 15.45 (10) A, α = 77.37 (8), β = 89.75 ( 8)°, γ = 61.69 (7)°, V = 1501 (2) A3 and Z = 1. 在晶体骨架中,三维(3D)结构的组装是通过分子间氢键和范德华相互作用形成的. 进行光谱表征以阐明结构(UV-Vis、FTIR、31P MAS-NMR和荧光特性)。在氩气氛下通过TG-DTA图研究热稳定性。此外,进行了 3-D Hirshfeld 表面与 2-D 指纹图的结合。还评估了该化合物的抗氧化活性;进行了四项体外测试,1,1-二苯基-2-苦基肼
