Ni2AlO4 crystallizes in the tetragonal I4_1/a space group. Ni(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Al(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ni(1) and one Al(1) atom.
Ni2AlO4 crystallizes in the tetragonal I4_1/a space group. Ni(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two shorter (1.85 Å) and two longer (1.86 Å) Ni(1)-O(1) bond lengths. Al(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. All Al(1)-O(1) bond lengths are 1.89 Å. O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ni(1) and one Al(1) atom.
