Perovskite manganite material has been extensively investigated because it has many attractive properties. In this paper, crystal structure of La 0.7 Ag 0.1 Ca 0.2 MnO 3 (LACMO1) and La 0.65 Ag 0.15 Ca 0.2 MnO 3 (LACMO15) materials will be reported. LACMO1 and LACMO15 materials were synthesized by sol-gel method with sintering temperature 900°C for 24h. Structural properties of LACMO1 and LACMO15 materials were characterized using X-Ray Diffractometer (XRD). The characterized results show a crystal structure transition from orthorhombic (Pnma spacegroup) to rhombohedral ( space group) along with increasing the concentration of Ag doping. The crystal structure transition show there is a distortion of the material structure caused by Ag-doping. Increasing the concentration of Ag doping may affect the tolerance factor (t) that used to measure the degree of distortion of a perovskite.
