Materials Data on Ba2Br2O by Materials Project
Ba2OBr2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Ba2+ is bonded in a 2-coordinate geometry to two equivalent O2- and five equivalent Br1- atoms. Both Ba–O bond lengths are 2.54 Å. There are a spread of Ba–Br bond distances ranging from 3.37–3.65 Å. O2- is bonded to four equivalent Ba2+ atoms to form distorted edge-sharing OBa4 tetrahedra. Br1- is bonded in a 5-coordinate geometry to five equivalent Ba2+ atoms.
