Abstract
X-ray diffraction method has been used to determine the crystal structure of the ternary compound Cu₂GeSe₃. A complete poder data is presented; and their analysis by Ito's method gives a Triclinic superlattice for the bended sphalerite unit cell of Cu₂GeSe₃ compound, with the lattice constants of a= 3.9381 A°, b= 22.3796 A°, and c= 11.5626 A° and the angles are α= 90.039°, β= 89.592° and γ= 89.945°.
