La2(ZnGe2)3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 14-coordinate geometry to two equivalent Zn(2), four equivalent Zn(1), two equivalent Ge(2), two equivalent Ge(3), and four equivalent Ge(1) atoms. In the second La site, La(2) is bonded in a 14-coordinate geometry to two equivalent Zn(2), four equivalent Zn(1), two equivalent Ge(2), two equivalent Ge(3), and four equivalent Ge(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to two equivalent La(1), two equivalent La(2), two equivalent Ge(2), and two equivalent Ge(3) atoms to form a mixture of distorted face and edge-sharing ZnLa4Ge4 tetrahedra. In the second Zn site, Zn(2) is bonded in a 5-coordinate geometry to two equivalent La(1), two equivalent La(2), one Ge(3), and four equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to one La(1), one La(2), one Zn(2), and three equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent La(1), two equivalent La(2), and four equivalent Zn(1) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent La(1), two equivalent La(2), one Zn(2), and four equivalent Zn(1) atoms.
