926-930Non-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 natur
