The material described by Bi2O3 crystallizes in the orthorhombic Pbcn space group. Bi(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing BiO5 square pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Bi(1) atoms to form edge-sharing OBi4 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Bi(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
