The compound described by Yb5Sb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 5-coordinate geometry to five equivalent Sb(1) atoms. In the second Yb site, Yb(2) is bonded to six equivalent Sb(1) atoms to form a mixture of distorted edge, corner, and face-sharing YbSb6 octahedra. The corner-sharing octahedral tilt angles are 36°. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Yb(2) and five equivalent Yb(1) atoms. is represented by the CIF card [CIF]
