NaTaWO6 crystallizes in the orthorhombic Imma space group. Na(1) is bonded in a hexagonal planar geometry to two equivalent O(3) and four equivalent O(1) atoms. Ta(1) is bonded to two equivalent O(3) and four equivalent O(1) 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 39-43°. W(1) is bonded to two equivalent O(2) and four equivalent O(1) 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 36-39°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), one Ta(1), and one W(1) atom. 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 4-coordinate geometry to two equivalent Na(1) and two equivalent Ta(1) atoms.
