A semi-organic nonlinear optical crystal of urea mercury chloride Hg(CH4N2O)Cl2, have been grown by the slow evaporation technique. The grown crystals were subjected to various characterization techniques, such as single crystal XRD, powder X-ray diffraction analysis, FTIR, UV–visible and TG/DTA analysis. The crystal was characterized by energy dispersive X-ray analysis. The dielectric constant and dielectric loss have been studied. The low dielectric constant and dielectric loss suggests that this material is a good candidate for micro-electronics applications. The photoconductivity property of the grown crystal is also studied. Second harmonic generation was confirmed by the Kurtz and Perry powder technique..
