Abstract
LiCrSi2O6 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 3-coordinate geometry to seven O2- atoms. There are a spread of Li–O bond distances ranging from 1.99–2.83 Å. In the second Li1+ site, Li1+ is bonded in a 2-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.01–2.57 Å. There are two inequivalent Cr3+ sites. In the first Cr3+ site, Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with five SiO4 tetrahedra, an edgeedge with one CrO6 octahedra, and an edgeedge with one SiO4 tetrahedra. There are a spread of Cr–O bond distances ranging from 1.95–2.12 Å. In the second Cr3+ site, Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six SiO4 tetrahedra and edges with two equivalent CrO6 octahedra. There are a spread of Cr–O bond distances ranging from 2.02–2.04 Å. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three CrO6 octahedra andmore »
