Materials Data on Li3Cr2(AsO4)3 by Materials Project

Li3Cr2(AsO4)3 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Li1+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.33 Å) and four longer (2.47 Å) Li–O bond lengths. Cr3+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent AsO4 tetrahedra. All Cr–O bond lengths are 2.01 Å. As5+ is bonded to four equivalent O2- atoms to form AsO4 tetrahedra that share corners with four equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 50°. All As–O bond lengths are 1.73 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Cr3+, and one As5+ atom.
