Materials Data on Na3BiO3 by Materials Project
Na3BiO3 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Na1+ is bonded to five equivalent O2- atoms to form a mixture of corner and edge-sharing NaO5 square pyramids. There are a spread of Na–O bond distances ranging from 2.37–2.50 Å. Bi3+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. All Bi–O bond lengths are 2.10 Å. O2- is bonded to five equivalent Na1+ and one Bi3+ atom to form a mixture of corner and edge-sharing ONa5Bi octahedra. The corner-sharing octahedral tilt angles are 18°.
