Abstract
X-ray diffraction method has been used to determine the crystal structure of the ternary compound Cu2GeSe3. A complete powder 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°.
