Metal-organic coordination complex crystal ATCC has been synthesized by slow evaporation technique. The grown crystal was characterized by single crystal XRD technique to determine the cell parameters. The second harmonic generation (SHG) measurement confirms that the ATCC has nonlinear optical property. The UV-VIS-NIR spectroscopic studies revealed that the grown crystal has good optical transparency. The functional groups have been identified using FT-IR spectrum. The mechanical strength of the grown crystal was found from Vickers micro hardness measurement and the thermal stabilities were determined with the aid of thermo gravimetric analysis (TGA) and differential thermal analysis (DTA). The surface morphology was studied by using scanning electron microscope (SEM) and atomic force microscopy (AFM).
