Sb(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 Sb(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-57°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-57°. 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 Sb(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Sb(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to two equivalent W(1) atoms.
