KSbWO6 crystallizes in the orthorhombic Ima2 space group. K(1) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(4) atoms. W(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra and corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-42°. Sb(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra and corners with four equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-47°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Sb(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 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 3-coordinate geometry to one K(1), one W(1), and one Sb(1) atom.
KSbWO6 crystallizes in the orthorhombic Ima2 space group. K(1) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(4) atoms. The K(1)-O(1) bond length is 2.87 Å. Both K(1)-O(4) bond lengths are 2.93 Å. W(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra and corners with four equivalent Sb(1)O6 octahedra.
