摘要
The crystal structures of the compounds Y3CuSiS7 and Y3CuSiSe7 (La3CuSiS7 structure type, space group P63, Pearson symbol hP24) were determined by means of X-ray single crystal diffraction: a = 0.9854(1) nm, c = 0.5656(1) nm, R1 = 0.0267 (Y3CuSiS7); a = 1.0269(1) nm, c = 0.5954(1) nm, R1 = 0.0346 (Y3CuSiSe7). The packing of the Y-centered distorted trigonal prisms, Cu-centered triangles and Si-centered tetrahedra along the c direction in the structures of Y3CuSiS7 and Y3CuSiSe7 compounds exists.
