Abstract

LiCrAlO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are one shorter (1.96 Å) and two longer (2.04 Å) Li–O bond lengths. Cr4+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with three equivalent AlO6 octahedra, edges with two equivalent CrO6 octahedra, and edges with two equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 26–51°. There are a spread of Cr–O bond distances ranging from 1.86–2.05 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with three equivalent CrO6 octahedra, edges with two equivalent CrO6 octahedra, and edges with four equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 26–51°. There are a spread of Al–O bond distances ranging from 1.87–1.95 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to one Cr4+ and three equivalent Al3+ atoms to form OAl3Cr trigonal pyramids that share a cornercorner with one OLi2AlCr2 trigonal bipyramid, corners with two equivalent OAl3Cr trigonal pyramids, edges with two equivalent OLi2AlCr2 trigonal bipyramids, and edges with two equivalent OAl3Cr trigonal pyramids.
