In the center of the molecule—and thus where it always is for fluorine chemists—sits one of the fluorine atoms of the PF3 unit in the twelvemembered heterocycle P6N6F (structure shown on the right). However, in the eight-membered ring in the P4N4F ion, the corresponding fluorine atom interacts with the three other phosphorus centers and forms the apex of a highly distorted square pyramid.
