KTaWO6 crystallizes in the orthorhombic Ima2 space group. K(1) is bonded in a hexagonal planar geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. Ta(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form TaO6 octahedra that share corners with two equivalent Ta(1)O6 octahedra and corners with four equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-39°. 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 Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-38°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Ta(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 3-coordinate geometry to one K(1), one Ta(1), and one W(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one K(1), one Ta(1), and one W(1) atom.
