La2AlGe is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Amm2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to three equivalent Al(1) and four equivalent Ge(1) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to four equivalent Al(1) and three equivalent Ge(1) atoms. Al(1) is bonded in a 9-coordinate geometry to three equivalent La(1), four equivalent La(2), and two 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 Al(1) atoms.

In the first La site, La(1) is bonded in a 7-coordinate geometry to three equivalent Al(1) and four equivalent Ge(1) atoms. There are two shorter (3.33 Å) and one longer (3.40 Å) La(1)-Al(1) bond length. All La(1)-Ge(1) bond lengths are 3.23 Å. In the second La site, La(2) is bonded in a 7-coordinate geometry to four equivalent Al(1) and three equivalent Ge(1) atoms. All La(2)-Al(1) bond lengths are 3.25 Å. There is one shorter (3.33 Å) and two longer (3.38 Å) La(2)-Ge(1) bond lengths. Al(1) is bonded in a 9-coordinate geometry to three equivalent La(1), four equivalent La(2), and two equivalent Ge(1) atoms. Both Al(1)-Ge(1) bond lengths are 2.62 Å. Ge(1) is bonded in a 9-coordinate geometry to three equivalent La(2), four equivalent La(1), and two equivalent Al(1) atoms.
