The material structure described by Bi2O3 is Corundum-like structured and crystallizes in the trigonal R-3c space group. Bi(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded to four equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra. is represented by the CIF file [CIF]
