The material structure described by Y5Sb3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Y sites. In the first Y site, Y(1) is bonded in a 6-coordinate geometry to two equivalent Sb(2) and four equivalent Sb(1) atoms. In the second Y site, Y(2) is bonded in a 5-coordinate geometry to two equivalent Sb(2) and three equivalent Sb(1) atoms. In the third Y site, Y(3) is bonded in a 5-coordinate geometry to one Sb(2) and four equivalent Sb(1) atoms. In the fourth Y site, Y(4) is bonded to one Sb(2) and four equivalent Sb(1) atoms to form distorted edge-sharing YSb5 square pyramids. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to two equivalent Y(1), two equivalent Y(3), two equivalent Y(4), and three equivalent Y(2) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to one Y(3), one Y(4), two equivalent Y(1), and four equivalent Y(2) atoms. is represented by the CIF file [CIF]
