The structure described by Bi(WO4)2 crystallizes in the monoclinic P2/c space group. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Bi(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-58°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-58°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one W(1) and one Bi(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Bi(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one Bi(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to two equivalent W(1) atoms. is represented by the CIF file [CIF]
