The crystal structure described by K2SnO6 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. Sn(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form SnO6 octahedra that share corners with two equivalent O(2)K2SnO tetrahedra and edges with two equivalent Sn(1)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent K(1) and one O(1) atom. In the second O site, O(2) is bonded to two equivalent K(1), one Sn(1), and one O(2) atom to form OK2SnO tetrahedra that share  a cornercorner with one Sn(1)O6 octahedra and corners with three equivalent O(2)K2SnO tetrahedra. The corner-sharing octahedral tilt angles are 67°. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
