Zusammenfassung:Manganese mercury thiocyanate bis-dimethyl sulfoxide (MMTD), a novel organo-metallic nonlinear optical (NLO) crystal, was grown by a slow evaporation technique over a period of 30 days. The grown crystal was subjected to single crystal X-ray diffraction to determine the unit cell parameters. The optical properties of MMTD were investigated by UV–Vis–NIR, FTIR and FT-Raman spectroscopic techniques. The second harmonic generation (SHG) efficiency of the sample was measured using a Q-switched, mode-locked Nd:YAG laser and the results were compared with urea and manganese mercury thiocyanate (MMTC). The thermal parameters, such as the thermal diffusivity ( α), thermal effusivity ( e), thermal conductivity ( k) and heat capacity ( c p) of MMTD were measured by the photopyroelectric (PPE) technique and the results are discussed. The dielectric response and mechanical properties of MMTD have also been investigated and reported.
