The material described by U6Fe crystallizes in the tetragonal I4/mcm space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a distorted T-shaped geometry to five equivalent U(1) and eight equivalent U(2) atoms. In the second U site, U(2) is bonded in a 4-coordinate geometry to one U(2), four equivalent U(1), and two equivalent Fe(1) atoms. Fe(1) is bonded in a 10-coordinate geometry to eight equivalent U(2) and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
