The crystal structure described by Bi2TiO5 crystallizes in the orthorhombic Cmc2_1 space group. Ti(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form corner-sharing TiO4 tetrahedra. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ti(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 distorted corner and edge-sharing OBi4 tetrahedra. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent Ti(1) atoms. is represented by the CIF file [CIF]
