The compound described by C2BiO5 crystallizes in the orthorhombic Pnma space group. C(1) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing BiO6 pentagonal pyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to one C(1) and one Bi(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one C(1) and one Bi(1) atom. is represented by the CIF file [CIF]
