The structure described by NaHoO2 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form NaO6 octahedra that share corners with two equivalent Na(2)O6 octahedra, corners with two equivalent Ho(1)O6 octahedra, corners with two equivalent Ho(2)O6 octahedra, edges with two equivalent Na(1)O6 octahedra, edges with three equivalent Na(2)O6 octahedra, edges with three equivalent Ho(2)O6 octahedra, and edges with four equivalent Ho(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-13°. In the second Na site, Na(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form NaO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with two equivalent Ho(1)O6 octahedra, corners with two equivalent Ho(2)O6 octahedra, edges with two equivalent Na(2)O6 octahedra, edges with three equivalent Na(1)O6 octahedra, edges with three equivalent Ho(1)O6 octahedra, and edges with four equivalent Ho(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 1-13°. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form HoO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with two equivalent Na(2)O6 octahedra, corners with two equivalent Ho(2)O6 octahedra, edges with two equivalent Ho(1)O6 octahedra, edges with three equivalent Na(2)O6 octahedra, edges with three equivalent Ho(2)O6 octahedra, and edges with four equivalent Na(1)O6 octahedra.

The corner-sharing octahedral tilt angles range from 1-13°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), two equivalent Na(2), one Ho(1), and two equivalent Ho(2) atoms to form a mixture of edge and corner-sharing ONa3Ho3 octahedra. The corner-sharing octahedral tilt angles range from 3-11°.
