Synthesis, structural, optical and thermal studies on 3,5-diethyl-2, 6-di (4-methoxyphenyl)-4-oxopiperidinium chloride

• The new organic crystal, 3, 5-diethyl-2, 6-di (4-methoxyphenyl)-4-oxopiperidinium chloride (DMOC) was synthesized by slow evaporation method.
• Crystal structure was solved for the first time.
• DMOC crystal has wide optical band gap of 4.45 eV.

A new organic compound 3, 5-diethyl-2, 6-di(4-methoxyphenyl)-4-oxopiperidinium chloride (DMOC) was synthesized and its crystals were grown from an ethanolic solution adopting 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 DMOC were recorded to elucidate its molecular structure. UV-vis-NIR spectral study showed that the grown crystal is transparent in the entire visible region. The thermal stability of DMOC was studied by thermogravimetric and differential thermal (TG-DTA) analyses.
