The crystal structure of the chalcogenide compounds CuCo 2 InTe 4 and CuNi 2 InTe 4 , two new members of the I-II 2 -III-VI 4 family, were characterized by Rietveld refinement using X-ray powder diffraction data. Both materials crystallize in the tetragonal space group I4 2m (No. 121), Z = 2, with a stannite-type structure, with the binaries CoTe and NiTe as secondary phases.
