CoAlO3 crystallizes in the triclinic P-1 space group. Co(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Al(1) is bonded in a distorted bent 150 degrees geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Co(1) and one Al(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Co(1) and one Al(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Co(1) and one Al(1) atom.
