Abstract
The crystal structures of the R3CuSnSe7 (R = La, Ce, Pr, Nd, Sm, Gd, Tb and Dy) compounds (La3CuSiS7 structure type, space group P63, Pearson symbol hP24) were determined by means of X-ray powder diffraction: a = 1.07211(1)Â nm, c = 0.62770(1)Â nm, RI = 0.0613 (La3CuSnSe7); a = 1.06310(2)Â nm, c = 0.62562(1)Â nm, RI = 0.0737 (Ce3CuSnSe7); a = 1.05613(4)Â nm, c = 0.62532(3)Â nm, RI = 0.0964 (Pr3CuSnSe7); a = 1.05002(4)Â nm, c = 0.62523(2)Â nm, RI = 0.0808 (Nd3CuSnSe7); a = 1.03809(2)Â nm, c = 0.62848(2)Â nm, RI = 0.0745 (Sm3CuSnSe7); a = 1.02435(2)Â nm, c = 0.63409(2)Â nm, RI = 0.0834 (Gd3CuSnSe7); a = 1.01894(2)Â nm, c = 0.63642(2)Â nm, RI = 0.0881 (Tb3CuSnSe7); a = 1.01359(3)Â nm, c = 0.63809(3)Â nm, RI = 0.0916 (Dy3CuSnSe7).
