The crystal structure described by Sr2HoTaO6 is Orthorhombic Perovskite-derived structured and 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 Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 25-27°. Ta(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TaO6 octahedra that share corners with six equivalent Ho(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 25-27°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one Ho(1), and one Ta(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Ho(1), and one Ta(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 Ta(1) atom. is represented by the CIF file [CIF]
