Abstract

Ba6Mn4Co2O16Cl crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with three equivalent MnO6 octahedra, faces with four BaO12 cuboctahedra, faces with six MnO6 octahedra, and a faceface with one CoO4 tetrahedra. The corner-sharing octahedral tilt angles are 10°. There are a spread of Ba–O bond distances ranging from 2.90–3.23 Å. In the second Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to nine O2- and one Cl1- atom. There are a spread of Ba–O bond distances ranging from 2.71–2.96 Å. The Ba–Cl bond length is 3.03 Å. In the third Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to eight O2- and three equivalent Cl1- atoms. There are a spread of Ba–O bond distances ranging from 3.00–3.39 Å. There are a spread of Ba–Cl bond distances ranging from 3.29–3.44 Å. In the fourth Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with six equivalent MnO6 octahedra, faces with six equivalent BaO12 cuboctahedra, and faces with six equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 10°. There are a spread of Ba–O bond distances ranging from 2.91–3.11 Å. There are two inequivalent Mn+3.25+ sites. In the first Mn+3.25+ site, Mn+3.25+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, corners with three equivalent CoO4 tetrahedra, faces with three equivalent BaO12 cuboctahedra, and a faceface with one MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.91–2.05 Å. In the second Mn+3.25+ site, Mn+3.25+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, and faces with two MnO6 octahedra. There is three shorter (1.91 Å) and three longer (1.97 Å) Mn–O bond length. Co4+ is bonded to four O2- atoms to form CoO4 tetrahedra that share corners with three equivalent MnO6 octahedra, a cornercorner with one CoO4 tetrahedra, and a faceface with one BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 9–11°. There are a spread of Co–O bond distances ranging from 1.81–1.93 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to four Ba2+ and two Mn+3.25+ atoms.
