Materials Data on Ho2SeO2 by Materials Project
Ho2SeO2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Ho3+ is bonded in a 4-coordinate geometry to three equivalent Se2- and four equivalent O2- atoms. All Ho–Se bond lengths are 2.97 Å. All Ho–O bond lengths are 2.28 Å. Se2- is bonded to six equivalent Ho3+ atoms to form distorted SeHo6 octahedra that share corners with twelve equivalent OHo4 tetrahedra, edges with six equivalent SeHo6 octahedra, and edges with six equivalent OHo4 tetrahedra. O2- is bonded to four equivalent Ho3+ atoms to form OHo4 tetrahedra that share corners with six equivalent SeHo6 octahedra, corners with six equivalent OHo4 tetrahedra, edges with three equivalent SeHo6 octahedra, and edges with three equivalent OHo4 tetrahedra. The corner-sharing octahedra tilt angles range from 28–48°.
