The structure described by BBi2O5 crystallizes in the orthorhombic Cmc2_1 space group. B(1) is bonded in a trigonal planar geometry to one O(3) and two equivalent O(1) atoms. Bi(1) is bonded to one O(3), two equivalent O(1), and four equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing BiO7 pentagonal bipyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one B(1) and 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 corner and edge-sharing OBi4 tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to one B(1) and two equivalent Bi(1) atoms. is represented by the CIF file [CIF]
