• r-2,c-6-Bis (2-chlorophenyl)-c-3,t-3-dimethylpiperidin-4-one is a new class of organic NLO material.
• This crystal has important characteristics of thermal and mechanical properties.
• Non-centro symmetric crystal crystallizes in monoclinic space group P21.
• SHG efficiency of the crystal was found to be 3.83 times greater than that of KDP.
An organic NLO material viz., cis-2,6-bis(2-chlorophenyl)-3,3-dimethylpiperidin-4-one (2C3DMPO), has been synthesized and a slow evaporation technique was applied to produce a single crystal. X-ray diffraction study on the single crystal 2C3DMPO reveals a non-centro symmetric crystal, possessing a monoclinic space group P21 and prefers to adopt a chair conformation. The crystal has been characterised using UV, FT-IR and NMR spectral studies. Solubility study and mechanical study using micro hardness methods have also been carried out. Furthermore, the thermal stability of the crystal was established by TG/DTA. The second harmonic conversion efficiency of the crystal was determined using the Kurtz and Perry powder technique and the activity observed was 3.83 times greater than that of KDP.
