description: Mn3Co3(SnO8)2 is beta Vanadium nitride-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Mn+5.33+ sites. In the first Mn+5.33+ site, Mn+5.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent SnO6 octahedra, an edgeedge with one SnO6 octahedra, and edges with four equivalent CoO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Mn–O bond distances ranging from 1.91–1.94 Å. In the second Mn+5.33+ site, Mn+5.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent SnO6 octahedra, an edgeedge with one SnO6 octahedra, edges with two equivalent MnO6 octahedra, and edges with two equivalent CoO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Mn–O bond distances ranging from 1.91–1.94 Å. There are two inequivalent Co+2.67+ sites. In the first Co+2.67+ site, Co+2.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent SnO6 octahedra, an edgeedge with one SnO6 octahedra, edges with two equivalent MnO6 octahedra, and edges with two equivalent CoO6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of Co–O bond distances ranging from 1.87–1.92 Å. In the second Co+2.67+ site, Co+2.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent SnO6 octahedra, an edgeedge with one SnO6 octahedra, and edges with four equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Co–O bond distances ranging from 1.87–1.92 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with two equivalent CoO6 octahedra, corners with four equivalent MnO6 octahedra, an edgeedge with one MnO6 octahedra, and edges with two equivalent CoO6 octahedra. The corner-sharing octahedra tilt angles range from 51–53°. There are a spread of Sn–O bond distances ranging from 2.03–2.14 Å. In the second Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with four equivalent CoO6 octahedra, an edgeedge with one CoO6 octahedra, and edges with two equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of Sn–O bond distances ranging from 2.05–2.15 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mn+5.33+, one Co+2.67+, and one Sn4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Co+2.67+ and one Sn4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Mn+5.33+ and two equivalent Co+2.67+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Mn+5.33+ and two equivalent Co+2.67+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Mn+5.33+ and one Co+2.67+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Mn+5.33+, one Co+2.67+, and one Sn4+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Co+2.67+ and one Sn4+ atom.
