Materials Data on Li5CrO4 by Materials Project
Li5CrO4 is Spinel-like structured and crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are five inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent CrO4 tetrahedra, corners with four LiO4 tetrahedra, corners with six LiO4 trigonal pyramids, an edgeedge with one CrO4 tetrahedra, edges with two LiO4 tetrahedra, and an edgeedge with one LiO4 trigonal pyramid. There are a spread of Li–O bond distances ranging from 1.94–2.06 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with two equivalent CrO4 tetrahedra, corners with eight LiO4 tetrahedra, corners with two equivalent LiO4 trigonal pyramids, an edgeedge with one CrO4 tetrahedra, edges with two LiO4 tetrahedra, and an edgeedge with one LiO4 trigonal pyramid. There are a spread of Li–O bond distances ranging from 1.97–2.08 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four LiO4 tetrahedra, corners with four equivalent CrO4 tetrahedra, corners with four LiO4 trigonal pyramids, edges with two LiO4 tetrahedra, and edges with two LiO4 trigonal pyramids. There are two shorter (1.99 Å) and two longer (2.02 Å) Li–O bond lengths. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent CrO4 tetrahedra, corners with four LiO4 tetrahedra, corners with six LiO4 trigonal pyramids, an edgeedge with one CrO4 tetrahedra, edges with two LiO4 tetrahedra, and an edgeedge with one LiO4 trigonal pyramid. There are a spread of Li–O bond distances ranging from 1.97–2.04 Å. In the fifth Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with two equivalent CrO4 tetrahedra, corners with eight LiO4 tetrahedra, corners with two equivalent LiO4 trigonal pyramids, an edgeedge with one CrO4 tetrahedra, edges with two LiO4 tetrahedra, and an edgeedge with one LiO4 trigonal pyramid. There are a spread of Li–O bond distances ranging from 1.95–2.04 Å. Cr3+ is bonded to four O2- atoms to form distorted CrO4 tetrahedra that share corners with eight LiO4 tetrahedra, corners with four LiO4 trigonal pyramids, edges with two LiO4 tetrahedra, and edges with two LiO4 trigonal pyramids. There are a spread of Cr–O bond distances ranging from 1.90–1.94 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to five Li1+ and one Cr3+ atom to form a mixture of distorted edge and corner-sharing OLi5Cr octahedra. The corner-sharing octahedra tilt angles range from 50–62°. In the second O2- site, O2- is bonded to five Li1+ and one Cr3+ atom to form a mixture of distorted edge and corner-sharing OLi5Cr octahedra. The corner-sharing octahedra tilt angles range from 49–60°. In the third O2- site, O2- is bonded to five Li1+ and one Cr3+ atom to form a mixture of distorted edge and corner-sharing OLi5Cr octahedra. The corner-sharing octahedra tilt angles range from 49–62°. In the fourth O2- site, O2- is bonded to five Li1+ and one Cr3+ atom to form a mixture of edge and corner-sharing OLi5Cr octahedra. The corner-sharing octahedra tilt angles range from 53–60°.
