Zr5CuSn3 was prepared from the elements in an arc-melting furnace and investigated by X-ray diffraction of powders as well as of single crystals. The crystal structure was refined from four-circle diffractometer data: P63/mcm, a = 860.04(7) pm, c = 586.80(5) pm, V = 0.3759(1) nm3, Z = 2, wR2 = 0.0402 for 371 F2 values and 15 variables. A refinement of the occupancy parameters revealed that the copper position is occupied to only 95.3(8)% in the crystal used for the X-ray investigation. Zr5CuSn3 crystallizes in the Hf5CuSn3 type structure, a filled variant of the Mn5Si3 type. The main features of the Zr5CuSn3 structure are condensed Zr6 octahedra that are centered by copper atoms
