The crystal structure described by Rh3Y crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 12-coordinate geometry to three equivalent Rh(4) and nine equivalent Rh(1) atoms. In the second Y site, Y(2) is bonded in a distorted hexagonal planar geometry to three equivalent Rh(2), three equivalent Rh(3), and twelve equivalent Rh(1) atoms. There are four inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to two equivalent Y(2), three equivalent Y(1), one Rh(2), one Rh(3), one Rh(4), and four equivalent Rh(1) atoms to form distorted RhY5Rh7 cuboctahedra that share corners with two equivalent Rh(4)Y6Rh6 cuboctahedra, corners with fifteen equivalent Rh(1)Y5Rh7 cuboctahedra, edges with eight equivalent Rh(1)Y5Rh7 cuboctahedra, faces with three equivalent Rh(4)Y6Rh6 cuboctahedra, and faces with eleven equivalent Rh(1)Y5Rh7 cuboctahedra. In the second Rh site, Rh(2) is bonded in a 12-coordinate geometry to three equivalent Y(2), three equivalent Rh(3), and six equivalent Rh(1) atoms. In the third Rh site, Rh(3) is bonded in a 12-coordinate geometry to three equivalent Y(2), three equivalent Rh(2), and six equivalent Rh(1) atoms. In the fourth Rh site, Rh(4) is bonded to six equivalent Y(1) and six equivalent Rh(1) atoms to form RhY6Rh6 cuboctahedra that share corners with twelve equivalent Rh(1)Y5Rh7 cuboctahedra, edges with six equivalent Rh(4)Y6Rh6 cuboctahedra, and faces with eighteen equivalent Rh(1)Y5Rh7 cuboctahedra. is represented by the CIF file [CIF]
