The material described by Bi2O3 is Tungsten structured and crystallizes in the cubic I23 space group. The structure is zero-dimensional and consists of two Bi2O3 clusters. Bi(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Bi(1) atoms. is represented by the CIF card [CIF]
