The material structure described by Bi2O5 crystallizes in the monoclinic P2/c space group. Bi(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of edge and corner-sharing BiO6 octahedra. The corner-sharing octahedral tilt angles range from 4-32°. There are three inequivalent O sites. In the first O site, O(2) is bonded in a linear geometry to two equivalent Bi(1) atoms. In the second O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent Bi(1) atoms. In the third O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi(1) atoms. is represented by the CIF file [CIF]
