Materials Data on LiCrCSO7 by Materials Project
LiCrCSO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Li1+ is bonded in a 3-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.73 Å. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with four equivalent SO4 tetrahedra. There are a spread of Cr–O bond distances ranging from 1.99–2.06 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.24 Å) and two longer (1.33 Å) C–O bond length. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 36–48°. There are a spread of S–O bond distances ranging from 1.47–1.49 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Cr3+, and one C4+ 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 distorted bent 150 degrees geometry to one Cr3+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Cr3+, and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+, one Cr3+, and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cr3+ and one S6+ atom.
