Abstract: Single crystals of Pure L-Threonine manganese acetate (LTMA) and Lead (Pb2+) doped LTMA have been grown by the slow evaporation method grown successfully by slow evaporation method at 300C Temperature. Single crystal XRD study determines the crystal system and unit cell parameters, and it carried out volume variations. Powder XRD pattern confirm that there is change in the lattice points of pure and doped material. The prominent peaks confirm the positions of lattice points and crystal planes. EDAX analysis qualitatively ignored that the presence of Chemical composition in both crystals. The active functional groups of the crystal points are analyzed by FTIR spectrum. Optical property of the crystal studied by UV-Vis-NIR, shows that transmittance in the range of 267-1100 nm for pure LTMA and 200 -1100 nm for Pb2+ doped LTMA and energy band gaps also determined. The Hardness of the both crystals is studied by Vicker’s Micro hardness analysis.
