The compound described by Bi2O3 crystallizes in the triclinic P1 space group. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 1-coordinate geometry to one O(1) and three equivalent O(3) atoms. In the second Bi site, Bi(2) is bonded in a 5-coordinate geometry to one O(1), one O(3), and three equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Bi(1) and one Bi(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Bi(2) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Bi(2) and three equivalent Bi(1) atoms. is represented by the CIF card [CIF]
