HoBO3 is Calcite structured and crystallizes in the trigonal R-3c space group. Ho(1) is bonded to six equivalent O(1) atoms to form corner-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles are 58°. B(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a trigonal planar geometry to two equivalent Ho(1) and one B(1) atom.
