Materials Data on AlCr2O4 by Materials Project
Cr2AlO4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Cr+2.50+ sites. In the first Cr+2.50+ site, Cr+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.97 Å) and two longer (1.99 Å) Cr–O bond length. In the second Cr+2.50+ site, Cr+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.96 Å) and two longer (2.00 Å) Cr–O bond length. Al3+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. All Al–O bond lengths are 1.88 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal non-coplanar geometry to two Cr+2.50+ and one Al3+ atom. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to two Cr+2.50+ and one Al3+ atom.
