The material structure described by La3Pd4Ge4 crystallizes in the orthorhombic Immm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 14-coordinate geometry to four equivalent Pd(1), four equivalent Pd(2), two equivalent Ge(1), and four equivalent Ge(2) atoms. In the second La site, La(2) is bonded to four equivalent Pd(1) and eight equivalent Ge(1) atoms to form a mixture of edge and face-sharing LaGe8Pd4 cuboctahedra. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to two equivalent La(2), four equivalent La(1), one Ge(2), and two equivalent Ge(1) atoms. In the second Pd site, Pd(2) is bonded in a 4-coordinate geometry to four equivalent La(1) and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), two equivalent Pd(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent La(1), one Pd(1), and four equivalent Pd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
