Bi2WO6 crystallizes in the orthorhombic Aea2 space group. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 22°. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra.
Bi2WO6 crystallizes in the orthorhombic Aea2 space group. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 22°. Both W(1)-O(1) bond lengths are 1.88 Å. There are two shorter (1.81 Å) and two longer (2.15 Å) W(1)-O(2) bond lengths. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(3) atoms. There is one shorter (2.45 Å) and one longer (2.49 Å) Bi(1)-O(1) bond length. There are a spread of Bi(1)-O(3) bond distances ranging from 2.19-2.53 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra.
