K2SnOF6 crystallizes in the orthorhombic Fddd space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to two equivalent F(3), four equivalent F(1), and four equivalent F(2) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. Sn(1) is bonded in an octahedral geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. O(1) is bonded in a water-like geometry to two equivalent K(2) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), and one Sn(1) atom. In the second F site, F(2) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), and one Sn(1) atom. In the third F site, F(3) is bonded in a distorted T-shaped geometry to one K(1), one K(2), and one Sn(1) atom.
