Sb(WO3)5 crystallizes in the orthorhombic Cmme space group. There are three inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(4), one O(7), and two equivalent O(6) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 3-43°. In the second W site, W(2) is bonded to one O(1), one O(2), one O(5), one O(7), and two equivalent O(6) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 3-38°. In the third W site, W(3) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-43°. Sb(1) is bonded in a 2-coordinate geometry to two equivalent O(4) atoms. There are seven inequivalent O sites. In the first O site, O(3) is bonded in a linear geometry to two equivalent W(3) atoms. In the second O site, O(4) is bonded in a trigonal planar geometry to one W(1), one W(3), and one Sb(1) atom. In the third O site, O(5) is bonded in a bent 150 degrees geometry to one W(2) and one W(3) atom. In the fourth O site, O(6) is bonded in a linear geometry to one W(1) and one W(2) atom. In the fifth O site, O(7) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the sixth O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the seventh O site, O(2) is bonded in a distorted bent 150 degrees geometry to one W(1) and one W(2) atom.
