CsO4Br crystallizes in the tetragonal I4_1/amd space group. Cs(1) is bonded in a 12-coordinate geometry to twelve equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Br(1) atom. Br(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms.
CsO4Br crystallizes in the tetragonal I4_1/amd space group. Cs(1) is bonded in a 12-coordinate geometry to twelve equivalent O(1) atoms. There are four shorter (3.26 Å) and eight longer (3.46 Å) Cs(1)-O(1) bond lengths. O(1) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Br(1) atom. The O(1)-Br(1) bond length is 1.65 Å. Br(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms.
