The structure described by Y7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. In the second Y site, Y(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. In the third Y site, Y(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to one Y(1), two equivalent Y(3), and three equivalent Y(2) atoms. is represented by the CIF file [CIF]
