The crystal structure described by K2SnF6 crystallizes in the trigonal P-3m1 space group. K(1) is bonded to twelve equivalent F(1) atoms to form distorted KF12 cuboctahedra that share corners with six equivalent K(1)F12 cuboctahedra, corners with three equivalent Sn(1)F6 octahedra, faces with eight equivalent K(1)F12 cuboctahedra, and faces with three equivalent Sn(1)F6 octahedra. The corner-sharing octahedral tilt angles are 18°. Sn(1) is bonded to six equivalent F(1) atoms to form SnF6 octahedra that share corners with six equivalent K(1)F12 cuboctahedra and faces with six equivalent K(1)F12 cuboctahedra. F(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Sn(1) atom. is represented by the CIF file [CIF]
