X-ray crystal and DFT study of a potent anti-HIV-1 agent: 2-(5,5-Dioxido-3-phenylpyrazolo[4,3-c][1,2]benzothiazin-4(2H)-yl)-N′-[(3-nitrophenyl)methylidene]acetohydrazide
Preview AbstractThis study presents structural features of an important benzothiazine derivative -2-(5,5-Dioxido-3-phenylpyrazolo[4,3-c][1,2]benzothiazin-4(2H)-yl)-N′-[(3-nitrophenyl)methylidene]acetohydrazide. Molecular structure is characterized by single crystal XRD and compared with optimized geometry at B3LYP/6-31G(d,p) and PBE0/6-31G(d,p) levels of density functional theory (DFT). Simulated properties (1H-NMR & IR) are in good correlation with experimental results. Electronic properties (coefficients of HOMO and LUMO) are also presented.
