There are fourteen inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to two Li1+ and one Fe2+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to one Li1+ and one Fe2+ atom. In the third F1- site, F1- is bonded in a distorted water-like geometry to one Li1+ and two Fe2+ atoms. In the fourth F1- site, F1- is bonded in a 2-coordinate geometry to one Li1+ and two Fe2+ atoms. In the fifth F1- site, F1- is bonded in a 3-coordinate geometry to one Li1+ and two Fe2+ atoms. In the sixth F1- site, F1- is bonded in a 1-coordinate geometry to one Li1+ and two Fe2+ atoms. In the seventh F1- site, F1- is bonded in a 2-coordinate geometry to one Li1+ and two Fe2+ atoms. In the eighth F1- site, F1- is bonded in a 1-coordinate geometry to one Li1+ and two Fe2+ atoms. In the ninth F1- site, F1- is bonded in a 1-coordinate geometry to one Li1+ and two Fe2+ atoms. In the tenth F1- site, F1- is bonded in a distorted single-bond geometry to one Li1+ atom. In the eleventh F1- site, F1- is bonded in a distorted single-bond geometry to one Li1+ and one Fe2+ atom. In the twelfth F1- site, F1- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one Fe2+ atom. In the thirteenth F1- site, F1- is bonded in a 1-coordinate geometry to one Li1+ and two Fe2+ atoms. In the fourteenth F1- site, F1- is bonded in a 2-coordinate geometry to one Li1+ and one Fe2+ atom.« less
