The material structure described by La2Pd4GaAl3 crystallizes in the tetragonal P-4m2 space group. La(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 in a 4-coordinate geometry to four equivalent La(1) and four equivalent Al(2) atoms. In the second Pd site, Pd(2) is bonded in a 4-coordinate geometry to four equivalent La(1) and four equivalent Al(2) atoms. In the third Pd site, Pd(3) is bonded in a 5-coordinate geometry to four equivalent La(1), two equivalent Ga(1), one Al(2), and two equivalent Al(1) atoms. Ga(1) is bonded to four equivalent La(1) and four equivalent Pd(3) atoms to form distorted GaLa4Pd4 tetrahedra that share edges with four equivalent Ga(1)La4Pd4 tetrahedra and faces with four equivalent Al(1)La4Pd4 tetrahedra. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to four equivalent La(1) and four equivalent Pd(3) atoms to form distorted AlLa4Pd4 tetrahedra that share edges with four equivalent Al(1)La4Pd4 tetrahedra and faces with four equivalent Ga(1)La4Pd4 tetrahedra. In the second Al site, Al(2) is bonded in a 5-coordinate geometry to four equivalent La(1), one Pd(3), two equivalent Pd(1), and two equivalent Pd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
