Ho3SbO3 crystallizes in the monoclinic C2/m space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1), one O(3), and three equivalent O(1) atoms. In the second Ho site, Ho(2) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(1), one O(2), and two equivalent O(3) atoms. In the third Ho site, Ho(3) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(3), and three equivalent O(2) atoms. Sb(1) is bonded in a body-centered cubic geometry to two equivalent Ho(2), two equivalent Ho(3), and four equivalent Ho(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Ho(2) and three equivalent Ho(1) atoms to form a mixture of corner and edge-sharing OHo4 tetrahedra. In the second O site, O(2) is bonded to one Ho(2) and three equivalent Ho(3) atoms to form a mixture of corner and edge-sharing OHo4 trigonal pyramids. In the third O site, O(3) is bonded to one Ho(1), one Ho(3), and two equivalent Ho(2) atoms to form a mixture of distorted corner and edge-sharing OHo4 trigonal pyramids.

In the first Ho site, Ho(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1), one O(3), and three equivalent O(1) atoms. There are two shorter (3.35 Å) and two longer (3.40 Å) Ho(1)-Sb(1) bond lengths. The Ho(1)-O(3) bond length is 2.67 Å. There are two shorter (2.24 Å) and one longer (2.25 Å) Ho(1)-O(1) bond length. In the second Ho site, Ho(2) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(1), one O(2), and two equivalent O(3) atoms. Both Ho(2)-Sb(1) bond lengths are 3.22 Å. The Ho(2)-O(1) bond length is 2.19 Å. The Ho(2)-O(2) bond length is 2.29 Å. Both Ho(2)-O(3) bond lengths are 2.25 Å. In the third Ho site, Ho(3) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(3), and three equivalent O(2) atoms. Both Ho(3)-Sb(1) bond lengths are 3.18 Å. The Ho(3)-O(3) bond length is 2.20 Å. There are two shorter (2.26 Å) and one longer (2.40 Å) Ho(3)-O(2) bond length.
