The strong influence of single crystals in the present day technology is evident from the recent advancements in semiconductors, polarisers, transducers, infrared detectors, photosensitive materials and crystalline thin films for microelectronics and computer industries. Nonlinear optical crystals (NLO) are in great demand in view of their applications in areas like optical modulation, optical switching, frequency shifting and optical data storage for developing technologies in telecommunications and signal processing. Organometallic single crystals are specially noted among the new generation NLO crystal due their structural diversity and applications. In this present work, organometallic compounds of manganese mercury thiocyanate (MMTC) and Co2+ doped MMTC were synthesised and single crystals were grown by slow evaporation method. The grown crystals were subjected to various characterisation techniques like X-ray diffraction analysis, FT-IR analysis and UV spectroscopy. Dielectric and photo conductivity studies were also performed. The first chapter in the dissertation brings out the importance of organometallic NLO crystals. Literature survey on the NLO crystals is also included in this chapter. An introduction to solution growth techniques is given in the second chapter. All the characterization techniques used for the work are introduced in the third chapter. The fourth chapter describes the synthesis, growth and characterization studies of MMTC and Co2+ doped MMTC. The last chapter contains results and discussions leading to the conclusion.
