Yb4Sb2O is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a linear geometry to four equivalent Sb(1) and two equivalent O(1) atoms. In the second Yb site, Yb(2) is bonded in a distorted single-bond geometry to five equivalent Sb(1) and one O(1) atom. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms. O(1) is bonded to two equivalent Yb(2) and four equivalent Yb(1) atoms to form corner-sharing OYb6 octahedra. The corner-sharing octahedra are not tilted.
Yb4Sb2O is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a linear geometry to four equivalent Sb(1) and two equivalent O(1) atoms. All Yb(1)-Sb(1) bond lengths are 3.21 Å. Both Yb(1)-O(1) bond lengths are 2.31 Å. In the second Yb site, Yb(2) is bonded in a distorted single-bond geometry to five equivalent Sb(1) and one O(1) atom. There is one shorter (3.18 Å) and four longer (3.28 Å) Yb(2)-Sb(1) bond lengths. The Yb(2)-O(1) bond length is 2.57 Å. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms. O(1) is bonded to two equivalent Yb(2) and four equivalent Yb(1) atoms to form corner-sharing OYb6 octahedra. The corner-sharing octahedra are not tilted.
