The material described by Bi2O3 is Antimony trioxide structured and crystallizes in the orthorhombic Pccn space group. Bi(1) is bonded in a distorted pentagonal planar geometry to two equivalent O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent Bi(1) atoms. In the second O site, O(2) is bonded to four equivalent Bi(1) atoms to form distorted edge-sharing OBi4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
