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.
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 shorter (3.10 Å) and four longer (3.25 Å) Lu(1)-Fe(1) bond lengths. There are two shorter (3.08 Å) and four longer (3.29 Å) Lu(1)-Fe(2) bond lengths. There are two shorter (2.89 Å) and four longer (2.92 Å) Lu(1)-Ge(1) bond lengths. There are two inequivalent Fe sites.
