KTa2O6 crystallizes in the orthorhombic Imma space group. K(1) is bonded in a hexagonal planar geometry to two equivalent O(1) and four equivalent O(3) atoms. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedral tilt angles range from 36-38°. In the second Ta site, Ta(2) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedral tilt angles are 38°. There are three 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(2) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Ta(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 Ta(2) atom.
