Abstract: The Pure L-Threonine manganese acetate (LTMA) and Zn2+ doped LTMA Single crystals have been grown at 30ͦC by the slow evaporation method. The grown crystals were subjected to various characterizations as single crystal XRD, Powder XRD, FTIR, UV–Vis, EDAX and Microhardness analysis. The lattice parameters of the grown crystals determined as Orthorhombic by single crystal X-ray analysis and Zn2+ ions made the volume increases as 530 Å3 to 538 Å3 . EDAX analysis confirms the presence of Zn2+ ion in the host material. The functional group and optical behavior of the crystals were identified from FTIR. UV-Vis absorption spectrum analysis determines the energy band gap 6.3 eV and transmittance spectrum determines the lower cutoff wavelength of the grown crystal 200nm. Mechanical properties of the crystals studied by Vicker’s hardness and hardness load graph plotted.
