The structure described by Fe23B6 crystallizes in the cubic Fm-3m space group. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a cuboctahedral geometry to twelve equivalent Fe(3) atoms. In the second Fe site, Fe(2) is bonded in a distorted tetrahedral geometry to four equivalent Fe(4) atoms. In the third Fe site, Fe(3) is bonded in a distorted bent 150 degrees geometry to one Fe(1) and two equivalent B(1) atoms. In the fourth Fe site, Fe(4) is bonded in a distorted trigonal non-coplanar geometry to one Fe(2) and three equivalent B(1) atoms. B(1) is bonded in a 8-coordinate geometry to four equivalent Fe(3) and four equivalent Fe(4) atoms. is represented by the CIF file [CIF]
