BiO2 crystallizes in the monoclinic C2/c space group. Bi(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing BiO6 pentagonal pyramids. O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi(1) atoms.
BiO2 crystallizes in the monoclinic C2/c space group. Bi(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing BiO6 pentagonal pyramids. There are four shorter (2.22 Å) and two longer (2.27 Å) Bi(1)-O(1) bond lengths. O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi(1) atoms.
