The structure described by La2Ge3 crystallizes in the orthorhombic Imm2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms. In the second La site, La(2) is bonded in a 10-coordinate geometry to two equivalent Ge(2), four equivalent Ge(1), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 7-coordinate geometry to two equivalent La(1), four equivalent La(2), and one Ge(3) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent La(2), four equivalent La(1), and two equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Ge(1), and two equivalent Ge(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
