The material described by Ba2HoTaO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/m space group. Ba(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Ho(1)O6 octahedra, and faces with four equivalent Ta(1)O6 octahedra. Ho(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form HoO6 octahedra that share corners with six equivalent Ta(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-9°. Ta(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TaO6 octahedra that share corners with six equivalent Ho(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-9°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1), one Ho(1), and one Ta(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Ba(1), one Ho(1), and one Ta(1) atom. is represented by the CIF card [CIF]
