The material structure described by Ho8Sb3O8 crystallizes in the monoclinic C2 space group. There are four inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 3-coordinate geometry to two equivalent Sb(1), two equivalent Sb(2), one O(1), one O(4), and two equivalent O(2) atoms. In the second Ho site, Ho(2) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(4), and three 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(2), one O(3), and two equivalent O(4) atoms. In the fourth Ho site, Ho(4) is bonded in a 4-coordinate geometry to two equivalent Sb(1), two equivalent Sb(2), one O(2), and three equivalent O(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a body-centered cubic geometry to two equivalent Ho(1), two equivalent Ho(2), two equivalent Ho(3), and two equivalent Ho(4) atoms. In the second Sb site, Sb(2) is bonded in a body-centered cubic geometry to four equivalent Ho(1) and four equivalent Ho(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Ho(1) and three equivalent Ho(4) atoms to form a mixture of corner and edge-sharing OHo4 tetrahedra. In the second O site, O(2) is bonded to one Ho(3), one Ho(4), and two equivalent Ho(1) atoms to form a mixture of corner and edge-sharing OHo4 tetrahedra. In the third O site, O(3) is bonded to one Ho(3) and three equivalent Ho(2) atoms to form a mixture of corner and edge-sharing OHo4 trigonal pyramids. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Ho(1), one Ho(2), and two equivalent Ho(3) atoms. is represented by the CIF card [CIF]
