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.
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. There are a spread of Yb(1)-Sb(1) bond distances ranging from 3.06-3.62 Å. 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°. All Yb(2)-Sb(1) bond lengths are 3.26 Å. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Yb(2) and five equivalent Yb(1) atoms.
