CsBiO2 crystallizes in the monoclinic C2/c space group. Cs(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Bi(1) is bonded in a distorted see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded in a 5-coordinate geometry to three equivalent Cs(1) and two equivalent Bi(1) atoms.
CsBiO2 crystallizes in the monoclinic C2/c space group. Cs(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are a spread of Cs(1)-O(1) bond distances ranging from 3.02-3.27 Å. Bi(1) is bonded in a distorted see-saw-like geometry to four equivalent O(1) atoms. There are two shorter (2.09 Å) and two longer (2.32 Å) Bi(1)-O(1) bond lengths. O(1) is bonded in a 5-coordinate geometry to three equivalent Cs(1) and two equivalent Bi(1) atoms.
