Cs2BaO2 is Bixbyite (Mn,Fe)2O4-like structured and crystallizes in the orthorhombic Pbcn space group. Cs(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. Ba(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent Ba(1) atoms.
Cs2BaO2 is Bixbyite (Mn,Fe)2O4-like structured and crystallizes in the orthorhombic Pbcn space group. Cs(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are a spread of Cs(1)-O(1) bond distances ranging from 2.94-3.46 Å. Ba(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. There are two shorter (2.58 Å) and two longer (2.63 Å) Ba(1)-O(1) bond lengths. O(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent Ba(1) atoms.
