Abstract

BaO2 is hexagonal omega structure structured and crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two BaO2 sheets oriented in the (0, 1, 0) direction. Ba is bonded to eight equivalent O atoms to form a mixture of edge and face-sharing BaO8 hexagonal bipyramids. All Ba–O bond lengths are 2.77 Å. O is bonded in a distorted pentagonal planar geometry to four equivalent Ba and one O atom. The O–O bond length is 1.52 Å.
