Title: Materials Data on Li2AlCoO4 by Materials Project

Abstract

Li2CoAlO4 is Theoretical Carbon Structure-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent CoO4 tetrahedra, corners with four equivalent LiO4 tetrahedra, corners with four equivalent AlO4 tetrahedra, and an edgeedge with one CoO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.13 Å. Co3+ is bonded to four O2- atoms to form CoO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra, corners with four equivalent AlO4 tetrahedra, and edges with two equivalent LiO4 tetrahedra. There are a spread of Co–O bond distances ranging from 1.86–1.90 Å. Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four equivalent CoO4 tetrahedra and corners with eight equivalent LiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.77–1.79 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+, one Co3+, and one Al3+ atom to form a mixture of distorted edge and corner-sharing OLi2AlCo tetrahedra. In the second O2- site, O2- is bonded to two equivalent Li1+, one Co3+, andmore » one Al3+ atom to form corner-sharing OLi2AlCo tetrahedra. In the third O2- site, O2- is bonded to two equivalent Li1+, one Co3+, and one Al3+ atom to form a mixture of edge and corner-sharing OLi2AlCo trigonal pyramids.« less
