LaHoO3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form corner-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles range from 37-40°. In the second Ho site, Ho(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles are 37°. La(1) is bonded in a 7-coordinate geometry to two equivalent O(1), two equivalent O(2), and three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Ho(1), one Ho(2), and two equivalent La(1) atoms to form distorted corner-sharing OLa2Ho2 tetrahedra. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ho(2) and two equivalent La(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Ho(1) and three equivalent La(1) atoms.

In the first Ho site, Ho(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form corner-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles range from 37-40°. Both Ho(1)-O(1) bond lengths are 2.23 Å. There are two shorter (2.27 Å) and two longer (2.28 Å) Ho(1)-O(3) bond lengths. In the second Ho site, Ho(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles are 37°. Both Ho(2)-O(1) bond lengths are 2.26 Å. There are two shorter (2.25 Å) and two longer (2.27 Å) Ho(2)-O(2) bond lengths. La(1) is bonded in a 7-coordinate geometry to two equivalent O(1), two equivalent O(2), and three equivalent O(3) atoms. There is one shorter (2.35 Å) and one longer (2.70 Å) La(1)-O(1) bond length. There is one shorter (2.30 Å) and one longer (2.92 Å) La(1)-O(2) bond length. There is one shorter (2.36 Å) and two longer (3.06 Å) La(1)-O(3) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Ho(1), one Ho(2), and two equivalent La(1) atoms to form distorted corner-sharing OLa2Ho2 tetrahedra.
