The structure described by Dy4(FeB2)3 crystallizes in the trigonal R-3m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 6-coordinate geometry to three equivalent Fe(1) and six equivalent B(1) atoms. In the second Dy site, Dy(2) is bonded in a 6-coordinate geometry to three equivalent Fe(1) and six equivalent B(1) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 14-coordinate geometry to six equivalent Dy(1), six equivalent Dy(2), and two equivalent Fe(2) atoms. In the second Fe site, Fe(2) is bonded in a 7-coordinate geometry to one Fe(1) and six equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), two equivalent Fe(2), and three equivalent B(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
