The structure described by 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. is represented by the CIF file [CIF]
