Bi2WO6 crystallizes in the orthorhombic Pca2_1 space group. W(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 20-29°. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(4) and four equivalent O(5) atoms. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(6) is bonded to four equivalent Bi(2) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent Bi(2) atoms. In the third O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to two equivalent W(1) atoms. In the fifth O site, O(4) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent Bi(1) atoms. In the sixth O site, O(5) is bonded to four equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra.
