KPF6 crystallizes in the trigonal R-3 space group. K(1) is bonded to twelve equivalent F(1) atoms to form KF12 cuboctahedra that share corners with six equivalent P(1)F6 octahedra, edges with six equivalent K(1)F12 cuboctahedra, and faces with two equivalent P(1)F6 octahedra. The corner-sharing octahedral tilt angles are 32°. P(1) is bonded to six equivalent F(1) atoms to form PF6 octahedra that share corners with six equivalent K(1)F12 cuboctahedra and faces with two equivalent K(1)F12 cuboctahedra. F(1) is bonded in a single-bond geometry to two equivalent K(1) and one P(1) atom.

The corner-sharing octahedral tilt angles are 32°. There are six shorter (2.82 Å) and six longer (2.87 Å) K(1)-F(1) bond lengths. P(1) is bonded to six equivalent F(1) atoms to form PF6 octahedra that share corners with six equivalent K(1)F12 cuboctahedra and faces with two equivalent K(1)F12 cuboctahedra. All P(1)-F(1) bond lengths are 1.62 Å. F(1) is bonded in a single-bond geometry to two equivalent K(1) and one P(1) atom.
