Sr2HoBiO6 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Ho(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form HoO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-32°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Ho(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-32°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), one Ho(1), and one Bi(1) atom to form distorted corner-sharing OSr2HoBi tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Ho(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Ho(1), and one Bi(1) atom.
