ABSTRACT. Cadmium Dimethyl Sulfoxide Thiocyanate (CDST) organometallic crystal was grown from aqueous solution. The grown CDST crystals are characterized by single X-ray diffraction for structural analysis. Fourier Transformation Infrared analysis confirms the presence of functional groups in the CDST. UV- Visible analysis reveals that CDST is about 90% transparent in the entire visible region and UV lower cutoff wavelength is 236 nm. TGA and DTA studies reveal the physicochemical stability of the CDST and NLO study by Kurtz – Perry powder technique reveals that the CDST exhibits emission of green light and the second harmonic generation efficiency of CDTS was 1.2 times that of KDP.

Keywords: Organometallic crystal, FTIR, UV-Vis, TG/DTA, NLO.
