The crystal structure described by Ce2Pd4GaAl3 crystallizes in the tetragonal P-4m2 space group. Ce(1) is bonded in a 16-coordinate geometry to two equivalent Pd(1), two equivalent Pd(2), four equivalent Pd(3), two equivalent Ga(1), two equivalent Al(1), and four equivalent Al(2) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent Ce(1) and four equivalent Al(2) atoms to form distorted PdCe4Al4 tetrahedra that share corners with four equivalent Ga(1)Ce4Pd4 tetrahedra, corners with eight equivalent Al(1)Ce4Pd4 tetrahedra, edges with two equivalent Ga(1)Ce4Pd4 tetrahedra, edges with four equivalent Pd(1)Ce4Al4 tetrahedra, and faces with four equivalent Pd(2)Ce4Al4 tetrahedra. In the second Pd site, Pd(2) is bonded to four equivalent Ce(1) and four equivalent Al(2) atoms to form distorted PdCe4Al4 tetrahedra that share corners with four equivalent Al(1)Ce4Pd4 tetrahedra, corners with eight equivalent Ga(1)Ce4Pd4 tetrahedra, edges with two equivalent Al(1)Ce4Pd4 tetrahedra, edges with four equivalent Pd(2)Ce4Al4 tetrahedra, and faces with four equivalent Pd(1)Ce4Al4 tetrahedra. In the third Pd site, Pd(3) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Ga(1), one Al(2), and two equivalent Al(1) atoms. Ga(1) is bonded to four equivalent Ce(1) and four equivalent Pd(3) atoms to form distorted GaCe4Pd4 tetrahedra that share corners with four equivalent Pd(1)Ce4Al4 tetrahedra, corners with eight equivalent Pd(2)Ce4Al4 tetrahedra, edges with two equivalent Pd(1)Ce4Al4 tetrahedra, edges with four equivalent Ga(1)Ce4Pd4 tetrahedra, and faces with four equivalent Al(1)Ce4Pd4 tetrahedra. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to four equivalent Ce(1) and four equivalent Pd(3) atoms to form distorted AlCe4Pd4 tetrahedra that share corners with four equivalent Pd(2)Ce4Al4 tetrahedra, corners with eight equivalent Pd(1)Ce4Al4 tetrahedra, edges with two equivalent Pd(2)Ce4Al4 tetrahedra, edges with four equivalent Al(1)Ce4Pd4 tetrahedra, and faces with four equivalent Ga(1)Ce4Pd4 tetrahedra. In the second Al site, Al(2) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Pd(3), two equivalent Pd(1), and two equivalent Pd(2) atoms. is represented by the CIF card [CIF]
