The compound described by NaHoBO5 crystallizes in the monoclinic P2_1/m space group. Na(1) is bonded to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted NaO8 hexagonal bipyramids that share corners with two equivalent B(1)O4 tetrahedra, edges with two equivalent B(1)O4 tetrahedra, and faces with two equivalent Na(1)O8 hexagonal bipyramids. Ho(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), two equivalent O(4), and four equivalent O(1) atoms. B(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form BO4 tetrahedra that share corners with two equivalent Na(1)O8 hexagonal bipyramids and edges with two equivalent Na(1)O8 hexagonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Ho(1), and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Na(1), one Ho(1), and one B(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Na(1), one Ho(1), and one B(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1) and two equivalent Ho(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
