description: BaMn5(SO4)6 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent MnO6 octahedra, edges with six SO4 tetrahedra, and faces with two equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 46–51°. There are a spread of Ba–O bond distances ranging from 2.79–3.12 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent MnO6 octahedra, edges with six equivalent SO4 tetrahedra, and faces with two equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are six shorter (2.84 Å) and six longer (3.06 Å) Ba–O bond lengths. There are four inequivalent Mn+5.20+ sites. In the first Mn+5.20+ site, Mn+5.20+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with two equivalent BaO12 cuboctahedra, corners with six SO4 tetrahedra, and a faceface with one MnO6 octahedra.

In the second S+3.33+ site, S+3.33+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with five MnO6 octahedra and an edgeedge with one BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 21–55°. There are a spread of S–O bond distances ranging from 1.47–1.51 Å. In the third S+3.33+ site, S+3.33+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with five MnO6 octahedra and an edgeedge with one BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 16–53°. There are a spread of S–O bond distances ranging from 1.47–1.50 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Ba2+, one Mn+5.20+, and one S+3.33+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Ba2+, one Mn+5.20+, and one S+3.33+ atom.
