Abstract
The crystal structures of the compounds R3CuSe6 (R = Gd, Tb and Dy) (Sm3CuSe6 structure type, space group Pbcm, Pearson symbol oP40) and TbCu0.34Te2 (LaCu0.28Te2 structure type, space group Pbcm, Pearson symbol oP13.36) were determined by means of X-ray powder diffraction: a = 0.70902(3)Â nm, b = 0.77850(3)Â nm, c = 1.68576(7)Â nm, RI = 0.0882 (Gd3CuSe6); a = 0.70630(3)Â nm, b = 0.77396(3)Â nm, c = 1.67913(8)Â nm, RI = 0.0806 (Tb3CuSe6); a = 0.70463(4)Â nm, b = 0.76962(4)Â nm, c = 1.6680(1)Â nm, RI = 0.0928 (Dy3CuSe6); a = 0.75580(3)Â nm, b = 0.81753(3)Â nm, c = 0.60828(2)Â nm, RI = 0.0864 (TbCu0.34Te2).
