The structure described by Bi3O2F5 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 7-coordinate geometry to two equivalent O(1), one F(1), two equivalent F(3), and three equivalent F(2) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent O(1), two equivalent F(1), and two equivalent F(3) atoms. O(1) is bonded to two equivalent Bi(1) and two equivalent Bi(2) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to two equivalent Bi(1) and two equivalent Bi(2) atoms. In the second F site, F(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi(1) atoms. In the third F site, F(3) is bonded in a distorted trigonal planar geometry to one Bi(2) and two equivalent Bi(1) atoms. is represented by the CIF card [CIF]
