Materials Data on LiBiO2 by Materials Project

LiBiO2 crystallizes in the orthorhombic Ibam space group. The structure is two-dimensional and consists of two LiBiO2 sheets oriented in the (0, 0, 1) direction. Li1+ is bonded to four equivalent O2- atoms to form a mixture of distorted edge and corner-sharing LiO4 tetrahedra. All Li–O bond lengths are 2.00 Å. Bi3+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Bi–O bond distances ranging from 2.08–2.42 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to three equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to four equivalent Li1+ and one Bi3+ atom.
