The material described by LuFe4Ge2 crystallizes in the orthorhombic Pnnm space group. Lu(1) is bonded in a 18-coordinate geometry to six equivalent Fe(1), six equivalent Fe(2), and six equivalent Ge(1) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 3-coordinate geometry to three equivalent Lu(1) and three equivalent Ge(1) atoms. In the second Fe site, Fe(2) is bonded in a 3-coordinate geometry to three equivalent Lu(1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Lu(1), three equivalent Fe(1), and three equivalent Fe(2) atoms. is represented by the CIF card [CIF]
