The crystal structure of the quaternary compound Cu 2 NiGeS 4 , belonging to the system I 2 -II-IV-VI 4 , was characterized by Rietveld refinement using X-ray powder diffraction data. This material crystallize with a stannite structure in the tetragonal space group I2m (No 121), Z = 2, unit cell parameters a = 5.3384(1) A, c = 10.5732(3) A, V = 301.32(3) A 3 , acknowledged as a normal valence adamantane-structure.
