The material structure described by SnWO4 crystallizes in the orthorhombic Pnna space group. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 33°. Sn(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. There are two 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 Sn(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. is represented by the CIF file [CIF]
