Received: 01-11-2020 Accepted: 02-01-2021 Abstract: The single crystal of cis-2,6-bis(4-chlorophenyl)-3,3dimethylpiperidin-4-one (4C3DMPO) has been grown using a slow evaporation technique. 4C3DMPO is a non-centrosymmetric crystal which crystallizes in the orthorhombic system with space group Pna21. Benzene is used as a solvent for the crystal growth based on solubility studies. The mechanical studies, using microhardness methods, have also been carried out. The compound is characterised using UV, FT-IR and NMR spectral studies. Furthermore, the thermal stability of the crystal is established by TG/DTA. The nonlinear optical studies (SHG) of the crystal have been determined using the Kurtz and Perry powder technique and the activity observed is 2.5 times greater than that of KDP.
