Bi2O3 is Antimony trioxide-like structured and crystallizes in the tetragonal P-42_1c space group. Bi(1) is bonded in a 5-coordinate geometry to two equivalent O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Bi(1) atoms.
Bi2O3 is Antimony trioxide-like structured and crystallizes in the tetragonal P-42_1c space group. Bi(1) is bonded in a 5-coordinate geometry to two equivalent O(1) and three equivalent O(2) atoms. There is one shorter (2.13 Å) and one longer (2.65 Å) Bi(1)-O(1) bond length. There are a spread of Bi(1)-O(2) bond distances ranging from 2.14-2.37 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Bi(1) atoms.
