The compound described by LaO3 crystallizes in the triclinic P-1 space group. La(1) is bonded in a 2-coordinate geometry to two equivalent O(1), two equivalent O(2), and three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent La(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent La(1) and one O(3) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent La(1) and one O(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
