LaGe crystallizes in the orthorhombic Cmcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(1) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent La(2), four equivalent La(1), and two equivalent Ge(1) atoms.
LaGe crystallizes in the orthorhombic Cmcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(1) atoms. There are four shorter (3.17 Å) and four longer (3.33 Å) La(1)-Ge(1) bond lengths. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. There are four shorter (3.17 Å) and two longer (3.19 Å) La(2)-Ge(1) bond lengths. Ge(1) is bonded in a 9-coordinate geometry to three equivalent La(2), four equivalent La(1), and two equivalent Ge(1) atoms. There is one shorter (2.63 Å) and one longer (2.85 Å) Ge(1)-Ge(1) bond length.
