The structure described by Y5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Y(2) and five equivalent Y(1) atoms. is represented by the CIF file [CIF]
