In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Fe(3), one Fe(5), and one Fe(6) atom. In the third F site, F(3) is bonded in a distorted T-shaped geometry to one Fe(2), one Fe(4), and one Fe(5) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to one Fe(2), one Fe(3), and one Fe(4) atom.
