چکیده انگلیسی
The new hybrid [4-Cl-2-(CH3)C6H3NH3]6P6O18·2H2O was synthesized under normal conditions of temperature and pressure. Single crystal X-ray diffraction study was used to identify its structure. It revealed that this organic cyclohexaphosphate crystallized in the P1¯ triclinic space group with a = 10.41 (10) Ã
b = 10.94 (7) Ã
, c = 15.45 (10) Ã
, α = 77.37 (8), β = 89.75 (8)°, γ = 61.69 (7)°, V = 1501 (2) Ã
3 and Z = 1. In the crystal framework, the assembling of the three dimensional (3D) structure is formed by intermolecular hydrogen bonds and Van Der Waals interactions. A spectroscopic characterization was carried out to elucidate the structure (UV-Vis, FTIR, 31P MAS-NMR and fluorescent properties). The 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
