BiO2 crystallizes in the orthorhombic Ibam space group. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Bi(1) atoms. In the second O site, O(2) is bonded to four equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra.
BiO2 crystallizes in the orthorhombic Ibam space group. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. There is one shorter (2.18 Å) and one longer (2.66 Å) Bi(1)-O(1) bond length. There are a spread of Bi(1)-O(2) bond distances ranging from 2.32-2.66 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Bi(1) atoms. In the second O site, O(2) is bonded to four equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra.
