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.
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. There are three shorter (2.26 Å) and three longer (2.51 Å) Bi(1)-O(1) bond lengths. O(1) is bonded to four equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra.
