A new organic compound 3, 5-diethyl-2, 6-di (4-fluorophenyl)-4-oxopiperidinium chloride (DFOC) was synthesized and its crystal was grown from ethanolic solution adopting the slow evaporation solution growth technique. The structure of the grown crystal was analyzed by single crystal X-ray diffraction study. The compound crystallizes in the orthorhombic system with space group Pnma. 1H and 13C Fourier transform nuclear magnetic resonance spectra of DFOC were recorded to elucidate its molecular structure. UV–vis–NIR spectral study showed that the grown crystal is transparent in the entire visible region with the lower cut-off wavelength of 269 nm. The thermal stability of DFOC was studied by thermogravimetric and differential thermal (TG-DTA) analyses.
