Abstract: Non-linear optical single crystals of cadmium mercury tetrathiocyanate dimethylsulphoxide [CdHg(SCN)4(H6C2OS)2], (CMTD) were conveniently grown from a DMSO-water mixed solvent by slow solvent evaporation technique. The crystals were characterized by single crystal X-ray diffraction and FT IR. The grown crystals were also subjected to microhardness, dielectric and photoconductivity studies. The microhardness studies indicate that the Vickers hardness number of the crystal decreases with increase in applied load. The dielectric response of the crystal with varying frequencies is studied and reported. The photoconductivity studies confirm that the title compound has negative photoconducting nature
