The structure described by Bi2O3 crystallizes in the tetragonal P4_2/mcm space group. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. In the second O site, O(1) is bonded to four equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
