La3(PdZn)4 crystallizes in the orthorhombic Immm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to two equivalent Pd(1) and four equivalent Pd(2) atoms to form edge-sharing LaPd6 octahedra. In the second La site, La(2) is bonded in a 12-coordinate geometry to two equivalent Pd(1), four equivalent Pd(2), and six equivalent Zn(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to one La(1), two equivalent La(2), and six equivalent Zn(1) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Pd(2), and two equivalent Zn(1) atoms. Zn(1) is bonded in a 4-coordinate geometry to three equivalent La(2), one Pd(2), and three equivalent Pd(1) atoms.

In the first La site, La(1) is bonded to two equivalent Pd(1) and four equivalent Pd(2) atoms to form edge-sharing LaPd6 octahedra. Both La(1)-Pd(1) bond lengths are 3.11 Å. All La(1)-Pd(2) bond lengths are 3.08 Å. In the second La site, La(2) is bonded in a 12-coordinate geometry to two equivalent Pd(1), four equivalent Pd(2), and six equivalent Zn(1) atoms. Both La(2)-Pd(1) bond lengths are 3.06 Å. All La(2)-Pd(2) bond lengths are 3.17 Å. There are two shorter (3.17 Å) and four longer (3.18 Å) La(2)-Zn(1) bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to one La(1), two equivalent La(2), and six equivalent Zn(1) atoms. There are four shorter (2.61 Å) and two longer (2.80 Å) Pd(1)-Zn(1) bond lengths. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Pd(2), and two equivalent Zn(1) atoms. The Pd(2)-Pd(2) bond length is 2.94 Å.
