Materials Data on Li4Cr2C4SO16 by Materials Project
Li4Cr2C4SO16 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with four equivalent LiO6 octahedra, edges with two equivalent CrO6 octahedra, and an edgeedge with one SO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–81°. There are a spread of Li–O bond distances ranging from 2.15–2.33 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with four equivalent LiO6 octahedra, edges with two equivalent CrO6 octahedra, and an edgeedge with one SO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–81°. There are a spread of Li–O bond distances ranging from 2.12–2.46 Å. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share edges with four LiO6 octahedra. There are two shorter (2.01 Å) and four longer (2.02 Å) Cr–O bond lengths. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.28 Å) and two longer (1.30 Å) C–O bond length. S6+ is bonded to four equivalent O2- atoms to form SO4 tetrahedra that share edges with four LiO6 octahedra. All S–O bond lengths are 1.50 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr3+, and one C4+ atom. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cr3+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Cr3+, and one C4+ atom.
