摘要：

The crystal structures of the compounds YCuPbSe3 (structure type beta-BaLaCuSe3, space group Pnma, a = 1.05438 (5) nm, b = 0.40524 (2) nm, c = 1.33840 (5) nm, Pearson symbol oP24, R-1 = 0.0862), Y3CuSnSe7 (structure type La3CuSiS7 space group P6(3), a= 1.01270 (4)nm, c = 0.63651 nm, c = 0.63951 (1) nm, Pearson symbol hP24, R, =0.0547) and Y3CU0.685Se6 (structure type Sm-3 space group Pbcm, a = 0.70814 (2),CuSe6, rim, b = 0.77173 (2) nm, c = 1.66839 (4) nm, Pearson symbol oP38.74, R-1 = 0.0613) were determined by means of X-ray powder diffraction.
