Na3BiO3 crystallizes in the cubic I-43m space group. Na(1) is bonded to five equivalent O(1) atoms to form a mixture of corner and edge-sharing NaO5 square pyramids. Bi(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. O(1) is bonded to five equivalent Na(1) and one Bi(1) atom to form a mixture of corner and edge-sharing ONa5Bi octahedra. The corner-sharing octahedral tilt angles are 18°.
Na3BiO3 crystallizes in the cubic I-43m space group. Na(1) is bonded to five equivalent O(1) atoms to form a mixture of corner and edge-sharing NaO5 square pyramids. There are a spread of Na(1)-O(1) bond distances ranging from 2.31-2.45 Å. Bi(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. All Bi(1)-O(1) bond lengths are 2.08 Å. O(1) is bonded to five equivalent Na(1) and one Bi(1) atom to form a mixture of corner and edge-sharing ONa5Bi octahedra. The corner-sharing octahedral tilt angles are 18°.
