The compound described by Cs3HoO3 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Cs sites. In the first Cs site, Cs(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form distorted CsO4 tetrahedra that share corners with five equivalent Ho(1)O4 tetrahedra and  an edgeedge with one Cs(1)O4 tetrahedra. In the second Cs site, Cs(2) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. In the third Cs site, Cs(3) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. Ho(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form HoO4 tetrahedra that share corners with five equivalent Cs(1)O4 tetrahedra and  an edgeedge with one Ho(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 7-coordinate geometry to two equivalent Cs(1), two equivalent Cs(2), two equivalent Cs(3), and one Ho(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Cs(1), one Cs(3), two equivalent Cs(2), and two equivalent Ho(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Cs(1), one Cs(2), two equivalent Cs(3), and one Ho(1) atom. is represented by the CIF file [CIF]
